Fix inventory cache interface (#50446)
* Replace InventoryFileCacheModule with a better developer-interface

Use new interface for inventory plugins with backwards compatibility

Auto-update the backing cache-plugin if the cache has changed after parsing the inventory plugin

* Update CacheModules to use the config system and add a deprecation warning if they are being imported directly rather than using cache_loader

* Fix foreman inventory caching

* Add tests

* Add integration test to check that fact caching works normally with cache plugins using ansible.constants and inventory caching provides a helpful error for non-compatible cache plugins

* Add some developer documentation for inventory and cache plugins

* Add user documentation for inventory caching

* Add deprecation docs

* Apply suggestions from docs review

* Add changelog

minor_changes:
- inventory plugins - Inventory plugins that support caching can now use any cache plugin
shipped with Ansible.
deprecated_features:
- inventory plugins - Inventory plugins using self.cache is deprecated and will be removed
in 2.12. Inventory plugins should use self._cache as a dictionary to store results.
- cache plugins - Importing cache plugins directly is deprecated and will be removed in 2.12.
Cache plugins should use the cache_loader instead so cache options can be reconciled via
the configuration system rather than constants.
