[Improvement] Metrics examples & assorted changes (#706)

* Metrics examples & assorted changes

What has been done:

- Two new examples containing metrics sidecar information a well as metrics related annotations.
- Changed the `v1alpha` apiVersion to `v1`
- Changed the ArangoDB version to `3.7.10`.
- Walked through all examples for validity.

* Update production-cluster-with-metrics.yaml

* Resolved indentation for the `annotations`

* Update reboot-pod.yaml - fix typo
