Add a name length check when using the filename to name an assignment.

[GPugnet]

Context :
When an assignment has no name, the script use the filename to generate the assignment name.
Then the name is used to generate the assignment ID.

Issue :
If the name exceeds a maximum length of 48, the API returns a (400) Bad Request.
The script does not provide details about the issue.

Suggested fix :
Add a control and raise an error when using a filename longer than 48 characters.
Display more details about the API errors. In this case, the API returns an explicit error message we could display :

"error": {
        "code": "InvalidResourceName",
        "message": "The resource name 'policyAssignmentAF_ResourcesGroup_AuditMandatoryTags' exceeds the maximum length of 48."
    }

Great feedback. Let me investigate what the best options are here.

@GPugnet - I have validated with the Blueprint team that this specific limit is not an ARM limit but a limit imposed by the Blueprint feature. I'm working on adding some additional validation to ensure that if we hit this limit during import / export that we throw an error and terminate. Thanks for raising this up. Will be integrating a fix shortly and publish.

@GPugnet could you please review the latest merged version to see if it supports the requirement? I have also added the ability to run the script on PS CORE with a moduleMode parameter so that you can leverage the Az versus AzureRM Module set.

Validated character limit being honored and error thrown on failure. Closing this issue.
