Code Issues Proposed changes

Add kolla-kubernetes bootstrap capability to mariadb

Browse Source 
Kolla-kubernetes requires there be an alternative way to bootstrap
the container.  Kolla-kubernetes uses the Kubernetes API endpoint to
read information about the cluster so that the bootstrap process runs
serially.

Partially-implements: blueprint kolla-kubernetes-extended-dockerfiles
