Migrate prometheus operator from coreos (#6765)

* Create promethues-operator chart

Signed-off-by: Giancarlo Rubio <gianrubio@gmail.com>

* Fixes for stable/prometheus-operator

Changed:
- Update Prometheus to 2.4.3, alertmanager to 0.15.2
- Change some job labels - should refer to a label appearing on the service. Tried to keep this consistent with what was used in the coreos version
- Add confguration for using CoreDNS
- Add insecureSkipVerify to kubeApiServer
- Add `prometheus.additionalScrapeConfigs`, `prometheus.additionalAlertManagerConfigs`

- Add ability to deploy an operated prometheus without installing anything else
  - Switch `prometheus.serviceAccountName` to be based on `prometheus.fullname` to prevent clashes
- Fix `serviceMonitorSelector` typo
- Add `serviceMonitorNamespaceSelector` to values.yaml
- Fix grafana typo (#6765 (comment))

Add CoreDNS dashboard

- Fixed dashboard use of updated name metric
