Allow SCIM user extension creation without using a digital license

Would like the ability to provision users without digital license. Many users don't need a digital license until later on after onboarding, and the assignment of phone number/desk phone is a manual process so the user receives a phone number specific to their office location.

Currently new users will provision until all unassigned digital licenses are used up, then fail with "License limit has been reached". Only work around is to manually create the user extension with their email so that SCIM will auto update their user attributes.
