New modules btrfs_subvolume / btrfs_info (#5832)
* Initial implementation for new modules btrfs_subvolume and btrfs_info
* Improve/flesh out documentation. Add ability to target filesystem by uuid, label or device. Update tests to test targeting filesystem by each supported parameter and when only mountpoint.
* Updates for btrfs modules. Add missing copyright notices. Switch options to contains in return documentation. Update btrfs_subvolume to always use closest parent mount.
* Add maintainers for btrfs module(s) and remove unused class member cause lint failure.
* Add changelog fragment. Attempt to only run against the VMs as part of CI.
* Updates per code review. Remove changelog fragment. Switch use of map to list comprehension. Add trailing comma to last item in multi-line dicts. Clean up documentation with complete senstences for descriptions and correct/consistent use of macros.
* Improved error handling in btrfs_subvolume module: add custom exception type, favor exceptions over immediate call to fail_json and add single top level return for failure scenarios. Normalize name and snapshot_source parameters early in module execution and remove unecessary duplicate normalization throughout processing.
* Add azp/posix/3 to aliases per feedback
* Clean up automatic mounting. Prevent automount when check_mode=True. Immediately fail if a mount is identified as required and automount=True. Identify the minimal subset of subvolumes that need to be mounted instead of just finding a single common root.
* Skip btrfs_subvolume integration tests if btrfs-progs isn't successfully installed.
* Bump version_added for btrfs modules to 6.6.0. Ensure consistent trailing punctuation for module descriptions and document check_mode behavior as attribute description rather than a module level note.
* Remove unused imports from btrfs_subvolume module.
* Fix import.
* Docs improvements.
