Add status field in GlobalConfiguration custom resource

[vepatel]

Currently the GlobalConfiguration resource does not display any kind of Status field. In scenarios where a TransportServer or VirtualServer resource relies on the content in a GlobalConfiguration resource, it is useful to know if the GlobalConfiguration resource itself is miss-configured by checking the status of that GlobalConfiguration resource, rather than viewing the error in either the TransportServer or VirtualServer resource.

This update would allow an operations user to better debug a miss configured GlobalConfiguration resource on their own.

### Tasks
- [ ] Investigate how to add status to GC
- [ ] Update/Add pytests to assert GC status for those tests which currently test for events
