Get-MgDirectoryRoleMember should allow to filter by role template ID

[cnotin]

Currently, Get-MgDirectoryRoleMember only allows to filter by Directory Role ID:

   -DirectoryRoleId <String>

However, the underlying Graph API endpoint also allows to filter directly by Role Template ID:

You can use both the object ID and template ID of the directoryRole with this API. The template ID of a built-in role is immutable and can be seen in the role description on the Azure portal. For details, see Role template IDs.

It would be nice to have this possibility directly in Get-MgDirectoryRoleMember:

   -DirectoryRoleTemplateId <String>

It would avoid having to combine Get-MgDirectoryRole then Get-MgDirectoryRoleMember, like this:

$dirsync = Get-MgDirectoryRole -Filter "RoleTemplateId eq 'd29b2b05-8046-44ba-8758-1e26182fcf32'"
Get-MgDirectoryRoleMember -DirectoryRoleId $dirsync.Id

Thanks for bringing this to our attention.

The command does not currently support -roleTemplateId because alternate keys is currently disable at the OData CSDL to OpenAPI conversion level.

This API makes for a good case to start supporting alternate keys. I've transferred the issue to https://github.com/microsoftgraph/msgraph-metadata/issues/305 for this to supported

@peombwa : The dependency is now closed. Any other support needed?
