* Rework kube-state-metrics alerts:
- provide meaningful labels in summary as 'instance' label hardly makes sense in most of them
- rename some alerts to tell more accurate what the problem is
- adjust description trying to follow some kind of the message schema found in other alerts
* move changes to _data/rules.yml
* Update rules.yml
