[Security management] Workbench roles are listed as groups in a Keycloack setup

See attached videos for more details rhsso-rolesasgroups.mp4 .

The workbench roles (those defined at web.xml) shouldn't be listed as groups in the UI. Only those keycloack roles which are not defined in web.xml should be listed.

This can be reproduced with the lastest RH SSO 7.2 (Keycloack 3.4.3) and the latest workbench version from 7.7.x branch (ER2 build).
