feat: View default namespace for authorised users

[portly-halicore-76]

Feature Request

Describe the Feature Request

Give Paas users, defined via the paas.spec.groups, view access to the default namespace (named after the paas itself) generated by the operator.

Why:

PaasNs'es belonging to the Paas capabilities, are created in this default namespace. If, for some reason, an error is thrown in the reconciliation of these PaasNs'es, is it stated on the status block of those PaasNs'es in that default namespace. However, only a clusteradmin has rights to that namespace, as Paas users from the Paas, don't get access. So far self-service for our customers.

Describe Preferred Solution

Reconcile a view rolebinding for the default namespace, to each group specified in the Paas.
Document that a permission must be in place that all authenticated users may view PaasNs'es.

Describe Alternatives

Can't think of any.

Related Code

Probably in the rolebinding controller.
