In NiFi user identities can be forced to upper or lower case, can that functionality be implemented in NiFi Registry

When users log in to NiFi and NiFi Registry they typically type in usernames as lowercase.  In NiFi the user names can be transformed to uppercase (or lowercase) to match LDAP and Kerberos requirements. This becomes important when using Ranger which also seems to pattern match.  This capability to transform is not yet available in NiFi Registry.
