* Make sure include_role inherit variables from parent role
Setting the parent of task blocks generated by include_role after they
have been produced is not sufficient - it means the tasks don't have the
correct dependency chain set afterwards, and therefore, don't properly
inherit variables from outer roles.
In addition to manually setting the parents, pass the dep_chain when
compiling the role, such that variables are correctly imported.
Fixes#18540.
* Add tests for include_role
* Fix include_role variable inheritance for multiple parent levels
* Replace pipes.quote for shlex_quote
* More migration of pipes.quote to shlex_quote
Note that we cannot yet move module code over. Modules have six-1.4
bundled which does not have shlex_quote. This shouldn't be a problem as
the function is still importable from pipes.quote. It's just that this
has become an implementation detail that makes us want to import from
shlex instead.
Once we get rid of the python2.4 dependency we can update to a newer
version of bundled six module-side and then we're free to use
shlex_quote everywhere.
If the current ansible enviroment has a config setup
that doesn't use 'smart' as the configured transport
test_play_context would fail when it assumes the
transport will be 'smart'.
also remove condition to bypass setting user if user matches current user
this enables forcing user when set to the same user as current user and ignoring .ssh/config
while keeping .ssh/config with current user if nothing is specified.
* allow global no_log setting, no need to set at play or task level, but can be overriden by them
* allow turning off syslog only on task execution from target host (manage_syslog), overlaps with no_log functionality
* created log function for task modules to use, now we can remove all syslog references, will use systemd journal if present
* added debug flag to modules, so they can make it call new log function conditionally
* added debug logging in module's run_command
Due to the way we're now calculating delegate_to, if that value is based
on a loop variable ('item') we need to calculate all of the possible
delegated_to variables for that loop.
Fixes#12499
Also making PlayContext a child class of the Playbook Base class,
which gives it access to all of the FieldAttribute code to ensure
field values are correctly typed after post_validation
Fixes#11381
