optimize host_group_vars and vars plugin loading (#79945)
* Improve host_group_vars efficiency:

* normalize the basedir with `os.path.realpath()` once and cache it
* cache missing paths/files
* reduce the calls to `isinstance`

Add a couple more general improvements in vars/plugins.py get_vars_from_path():

* call `PluginLoader.all()` once for vars plugins and reload specific
  plugins subsequently
* don't reload legacy/builtin vars plugins that are not enabled

Add a test for host_group_vars and legacy plugin loading

Co-authored-by: Matt Davis <mrd@redhat.com>

* changelog

* Add a new is_stateless attribute to the vars plugin baseclass

update integration tests to be quieter and use the same test pattern

Fix deprecation and adjust test that didn't catch the issue (deprecation only occured when the value was False)

move realpath cache to host_group_vars (do not smuggle call state as instance data)

refactor under a single 'if cache:' statement

Call os.path.isdir instead of always calling os.path.exists first. Just call os.path.exists to differentiate between missing and non-directory.

remove call to super(VarsModule, self).get_vars()

use the entity name as the cache key instead of variable location

Remove isinstance checks and use a class attribute just in case any plugins are subclassing Host/Group

Replace startswith by checking index 0 of the name instead, since host/group names are required

* rename is_stateless to cache_instance to make it more clear what it does

* add plugin instance cache using the path to plugin loader

reduce loading stage option if a new instance isn't created

don't require a known subdir on PluginLoader instantiation for backwards
compatibility

rename attribute again

contain reading from/initializing cached instances to a plugin loader method

* Deprecate v2 vars plugins

* Refactor to use the cache in existing plugin loader methods

Rename the attribute again

Refactor host_group_vars with requested changes

Make changelog a bugfixes fragment

Add a deprecation fragment for v2 vars plugins.

Add type hints

* unbreak group_vars

* Apply suggestions from code review

* misc tweaks

* always cache instance by both requested and resolved FQ name
* add lru_cache to stage calculation to avoid repeated config consultation

* handle KeyError from missing stage option
