Provide kubernetes definition diffs in check_mode (#41471)

Browse source 
Move dict_merge from azure_rm_resource module to
module_utils.common.dict_transformations and add tests.

Use dict_merge to provide a fairly realistic, reliable
diff output when k8s-based modules are run in check_mode.

Rename unit tests so that they actually run and reflect
the module_utils they're based on.
