Become plugins (#50991)
* [WIP] become plugins

Move from hardcoded method to plugins for ease of use, expansion and overrides
  - load into connection as it is going to be the main consumer
  - play_context will also use to keep backwards compat API
  - ensure shell is used to construct commands when needed
  - migrate settings remove from base config in favor of plugin specific configs
  - cleanup ansible-doc
  - add become plugin docs
  - remove deprecated sudo/su code and keywords
  - adjust become options for cli
  - set plugin options from context
  - ensure config defs are avaialbe before instance
  - refactored getting the shell plugin, fixed tests
     - changed into regex as they were string matching, which does not work with random string generation
     - explicitly set flags for play context tests
 - moved plugin loading up front
 - now loads for basedir also
 - allow pyc/o for non m modules
 - fixes to tests and some plugins
 - migrate to play objects fro play_context
 - simiplify gathering
 -  added utf8 headers
 - moved option setting
 - add fail msg to dzdo
 - use tuple for multiple options on fail/missing
 - fix relative plugin paths
 - shift from play context to play
 - all tasks already inherit this from play directly
 - remove obsolete 'set play'
 - correct environment handling
 - add wrap_exe option to pfexec
 - fix runas to noop
 - fixed setting play context
 - added password configs
 - removed required false
 - remove from doc building till they are ready

future development:
  - deal with 'enable' and 'runas' which are not 'command wrappers' but 'state flags' and currently hardcoded in diff subsystems

* cleanup

  remove callers to removed func
  removed --sudo cli doc refs
  remove runas become_exe
  ensure keyerorr on plugin
  also fix backwards compat, missing method is attributeerror, not ansible error
  get remote_user consistently
  ignore missing system_tmpdirs on plugin load
  correct config precedence
  add deprecation
  fix networking imports
  backwards compat for plugins using BECOME_METHODS

* Port become_plugins to context.CLIARGS

This is a work in progress:
* Stop passing options around everywhere as we can use context.CLIARGS
  instead

* Refactor make_become_commands as asked for by alikins

* Typo in comment fix

* Stop loading values from the cli in more than one place

Both play and play_context were saving default values from the cli
arguments directly.  This changes things so that the default values are
loaded into the play and then play_context takes them from there.

* Rename BECOME_PLUGIN_PATH to DEFAULT_BECOME_PLUGIN_PATH

As alikins said, all other plugin paths are named
DEFAULT_plugintype_PLUGIN_PATH.  If we're going to rename these, that
should be done all at one time rather than piecemeal.

* One to throw away

This is a set of hacks to get setting FieldAttribute defaults to command
line args to work.  It's not fully done yet.

After talking it over with sivel and jimi-c this should be done by
fixing FieldAttributeBase and _get_parent_attribute() calls to do the
right thing when there is a non-None default.

What we want to be able to do ideally is something like this:

class Base(FieldAttributeBase):
    _check_mode = FieldAttribute([..] default=lambda: context.CLIARGS['check'])

class Play(Base):
    # lambda so that we have a chance to parse the command line args
    # before we get here.  In the future we might be able to restructure
    # this so that the cli parsing code runs before these classes are
    # defined.

class Task(Base):
    pass

And still have a playbook like this function:

---
- hosts:
  tasks:
  - command: whoami
    check_mode: True

(The check_mode test that is added as a separate commit in this PR will
let you test variations on this case).

There's a few separate reasons that the code doesn't let us do this or
a non-ugly workaround for this as written right now.  The fix that
jimi-c, sivel, and I talked about may let us do this or it may still
require a workaround (but less ugly) (having one class that has the
FieldAttributes with default values and one class that inherits from
that but just overrides the FieldAttributes which now have defaults)

* Revert "One to throw away"

This reverts commit 23aa883cbed11429ef1be2a2d0ed18f83a3b8064.

* Set FieldAttr defaults directly from CLIARGS

* Remove dead code

Toshio Kuratomi afdbb0d9d5 Save the command line arguments into a global context
* Once cli args are parsed, they're constant.  So, save the parsed args
  into the global context for everyone else to use them from now on.

* test for openstack inventory constructed functionality

this adds unit tests for the compose, groups, and keyed_var features
of the openstack inventory plugin

* fix constructed functionality in openstack inventory plugin

The compose, groups, and keyed_groups functionality of the openstack
inventory plugin was broken:

- the plugin was not passing the correct variables to the
  Constructable methods for compose and groups
- the plugin was simply never calling the appropriate method for
  implementing keyed_groups

* Ensure that the src file contents is converted to unicode in diff info. Fixes #45717

* The diff functionality in the callback plugins should have the
  to_text() calls removed since we're now doing it in ActionBase
* catching of UnicodeError and warnings in the callback diff
  functionality from 61d01f549f haven't been
  needed since we switched to to_text so remove them.
* Add a note to ActionBase's diff function giving an example of when the
  diff function will be inaccurate and how to fix it

* Fix callback get_diff() tests

I believe the unittests of callback's get_diff() were wrong.  They were
sending in a list where strings were expected.  Because previous code
was transforming the lists into strings via their repr, the previous
tests did not fail but they would have formatted the test cases output
in an odd way if we had looked at it.

Matthias Fuchs 7871027c9d Share the implementation of hashing for both vars_prompt and password_hash (#21215)
* Share the implementation of hashing for both vars_prompt and password_hash.
* vars_prompt with encrypt does not require passlib for the algorithms
  supported by crypt.
* Additional checks ensure that there is always a result.
  This works around issues in the crypt.crypt python function that returns
  None for algorithms it does not know.
  Some modules (like user module) interprets None as no password at all,
  which is misleading.
* The password_hash filter supports all parameters of passlib.
  This allows users to provide a rounds parameter, fixing #15326.
* password_hash is not restricted to the subset provided by crypt.crypt,
  fixing one half of #17266.
* Updated documentation fixes other half of #17266.
* password_hash does not hard-code the salt-length, which fixes bcrypt
  in connection with passlib.
  bcrypt requires a salt with length 22, which fixes #25347
* Salts are only generated by ansible when using crypt.crypt.
  Otherwise passlib generates them.
* Avoids deprecated functionality of passlib with newer library versions.
* When no rounds are specified for sha256/sha256_crypt and sha512/sha512_crypt
  always uses the default values used by crypt, i.e. 5000 rounds.
  Before when installed passlibs' defaults were used.
  passlib changes its defaults with newer library versions, leading to non
  idempotent behavior.

  NOTE: This will lead to the recalculation of existing hashes generated
        with passlib and without a rounds parameter.
        Yet henceforth the hashes will remain the same.
        No matter the installed passlib version.
        Making these hashes idempotent.

Fixes #15326
Fixes #17266
Fixes #25347 except bcrypt still uses 2a, instead of the suggested 2b.

* random_salt is solely handled by encrypt.py.
  There is no _random_salt function there anymore.
  Also the test moved to test_encrypt.py.
* Uses pytest.skip when passlib is not available, instead of a silent return.
* More checks are executed when passlib is not available.

* Moves tests that require passlib into their own test-function.

* Uses the six library to reraise the exception.

* Fixes integration test.

When no rounds are provided the defaults of crypt are used.
In that case the rounds are not part of the resulting MCF output.

This reverts commit 5c614a59a6.

* changes based on PR feedback and changelog fragment

* changes based on the review

* Fix tmpdir when makedirs failed so we just use the system tmp

* Let missing remote_tmp fail

If remote_tmp is missing then there's something more basic wrong in the
communication from the controller to the module-side.  It's better to
be alerted in this case than to silently ignore it.

jborean and I have independently checked what happens if the user sets
ansible_remote_tmp to empty string and !!null and both cases work fine.
(null is turned into a default value controller-side.  empty string
triggers the warning because it is probably not a directory that the
become user is able to use).
