This is uplift for CoreDNS to version 1.6.2 Upstream CoreDNS image has no tools inside like wget/dig and can't be used as is because pod probes will fail. Coredns pod has Liveness/Readiness probes which are just a shell script to run wget/dig to determine that CoreDNS is functional. So, decided to add tools for probes in promenade image and do refactoring. New endpoints for health check are running in side-car: /externalhealth - to do the same check like previous shell script, /selfcheck - to do check of the health of side-car itself. Main container should be pointed to check endpoint provided by side-car container. Change-Id: Ib7fcf309b6cc34a86eeeec6e2109988cfa862955

- Cluster bootstrapping
- Initial Genesis process results in a single node Kubernetes cluster with Under-cloud components deployed using Armada.
- Joining sufficient master nodes results in a resilient Kubernetes cluster.
- Destroy Genesis node after bootstrapping and re-provision as a normal node to ensure consistency.
- Life-cycle management
- Decommissioning of nodes.
- Updating Kubernetes version.
