KRACOEUS-6294: code changes for doc level role conversion

These are code changes needed once the data conversion has been done for doc level conversions.

Please note that these changes cannot be merged until https://github.com/kuali/kc-doc-access-conv has been executed against our master DBs.  Please review the kc-doc-access-conv program as a part of this PR.  Note that the kc-doc-access-conv program is a little rough because it is intended to be a conversion program and only used for data migration.
My line of thought on the naming convention is it is hopefully a temporary solution inside of the KcAuthorizationService and the workaround will be cleaned up once the migration is completed.  In other words we will be passing in the correct role names into KcAuthorizationService so the renaming logic wont be needed.  There is no detail values for roles by the way.
