check_openshift.py wants registry in router

[david-strejc]

Shouldn't be registry excluded from router check in check_openshift.py?

I am getting:
Critical: Pods: docker-registry-1-lwuw4: [Running] router [Missing]

[talset]

@david-strejc It is a pods check, for now we choose to check the registry and router in the same time. And print the stat for each. But maybe we should split in 2 checks because the registry or router are optionnal.

I will update this check also in order to check the number of router & registry running (regarding the replicas config)
