Unable to create objects with underscore in the name in registry-console in OCP 3.6

Issue

• Unable to use group with underscore in the name when setting permissions in Web UI
• An error is given in the Web UI when we attempt to use a group name that contains an underscore when setting permissions.
• Using oc commands, the groups with an underscore are accepted
• Creating an image stream with an underscore had the same behavior (able to create with oc/api but not in the web ui)

The member name contains invalid characters. Only letters, numbers, spaces and the following symbols are allowed: , = @ . _".
