Expand the Admin APIs section of the User Provisioning API

Currently the Admin APIs of the User Provisioning API (https://developer.atlassian.com/cloud/admin/user-provisioning/rest/api-group-admin-apis/#api-admin-user-provisioning-v1-org-orgid-user-aaid-onlydeleteuserindb-delete) allow admins to:

• Delete a user from the SCIM DB
• Get SCIM links for a given user or email
• Unlink a SCIM record from a user

If admins could also:

• Get unlinked SCIM records
• Relink a specific SCIM record
• Get SCIM links for a group name
• Resync a specific group to their org

They would be able to self-serve more of the common issues that require them to currently open support cases.
