This is a major refactor of the mariadb chart. A few things
are accomplished:
* The chart template layout is updated to match our keystone
chart, providing a more structure to the chart.
* The chart was updated to leverage StatefulSets, which requires
Kubernetes 1.5, and helm 2.1.0.
* The bootstrapping process was completely overhauled to support
the unique constraints of statefulsets, namely that they come up
one by one, needing the previous to be in a ready state before
the next is provisioned.
* The references to {{ .IP }} we removed and replaced with POD_IP
environmental passing and address binding was fixed in several
places for wsrep functionality. This may explain several oddities
with the previous setup causing mysterious and intermittent
database consistency issues.
