Marek Siarkowicz a559cb8be1 Unify references to group resource in metrics 
Skip apiserver_storage_objects as it's a stable metrics that doesn't
have "group" label. As defined in KEP-1209 adding a label is considered
a breaking change so this change should be done via deprecation and
introduction of new metric.

Tested via:
```
kubectl get --raw /metrics | grep -i apiservice | grep -v APIServiceRegistrationController | grep -v aggregator_unavailable_apiservice | python3 -c "import sys; print('\n'.join([k+' ' + v for k,v in {a.split('{')[0]:'{'+a.split('{')[1].split('}')[0]+'}' for a in sys.stdin.readlines() if '#' not in a and '_sum' not in a and '_bucket' not in a}.items()]))"
```

Before:
```
