Pull Request (PR) description

Initial release (take two).

CimInstances from DRG-generated resource has been 'flattened' to one level and property GroupDisplayName has been added to ensure cross-tenant capability.
I have omitted property 'lastHeartbeatDateTime' although it appears possible to modify it.

Not too sure about property 'CollectionId' in the ...AssignmentTarget CimInstance. Advice is welcome.

This Pull Request (PR) fixes the following issues

Posted an issue with regards to ConvertTo-IntunePolicyASsignment silently dropping assignments for groups that can't be read - this includes unit-tests failing in spite of required mocks. The easy workaround was to omit datatype *GroupAssignmentTarget from unit-tests. However in cross-tenant scenarios it's not implausible to reference a group that might not exist and in such a situation the resource should emit some sort of warning

updated resource to write event if a group is unknown - when getting assignments that refer to an unkown group, a warning is written, when setting assignments that refer to an unknown group, an error is written. I'm still undecided if that should cause an exception to avoid thinking that a configuration was updated if it really wasn't.
