* 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
* Changed 'Control Machine' to 'Control Node' in the documentation. Changing the term 'Control Machine' to 'Control Node', to be in line with the basic concepts here: https://docs.ansible.com/ansible/latest/network/getting_started/basic_concepts.html
Also for both entities; Control/Managed using the same common denominator 'Node' brings consistency.
* Updated reference links to new term.
Example instantiates an AnsibleError which derives from Exception but doesn't actually raise it like intended. This is misleading as it's not clear without examining the code for AnsibleError to know that it's not some function which would raise the exception automatically.
