Feature: flexible templates for custerroles

[elfrinjo]

Currently (if I am not entirely wrong) permission-manager supports namespaced role-templates. For clusterwide resource-access, there are only three roles (none, read-only, read-write) for all resources available.

I would very much appreciate to be able to define custom roles for cluster-resource-access and to assign them in the web-ui.

PS: Currently, every user needs to have a namespaced role. With this FR it might need to be possible to have a user with only clusterroles

Ye, it makes sense. Adding it to our internal backlog.

PD: Sorry for the late reply.
