Improve kubectl get output for our CRDs

[jlevesy]

What needs to be done?

We need to improve output of kubectl get escalations and kubectl get escalationpolicies to expiose relevant information.

• For escalation: status.State status.StateDetails and maybe a counter showing how many grants are Created comapted to the total grants.
• For escalation policies, eeeh. This needs to be given a bit of thinking. Maybe how may escalalations are active?

This could be done using additional printer colums in resources CRD.

• kubectl get escalations shows meaningful output
• kubectl get escalationpolicies shows meaningful output
