This PS adds a fronting tcp proxy with A/P to the backends. This
Change removes the issue of DB deadlocks when using multi-master
galera databases.

Remove 'connect_timeout' which defined in the '[client]' section which
surprisingly affects mysqldump by causing it to fail as it doesn't
understand this; we're not doing anything that depends on having this
value so this is safe.
This now means mysqldump works (as expected) and we can use the
packaged/pod version of mysqldump for backup purposes.

This PS simplifys the db start and init script, increasing
robustness of the mariadb chart on low end hardware. It also
removes some unrequired annotations and moves to more explicit
qualification of the clustering variables.

This PS removes the licence header from rendered output from tiller,
significantly reducing the configmap size of charts deployed to the
cluster.

This PS updates the MariaDB start script remove templated values
from being directly inserted into the script. It also moves the
root connection params to a secret to prevent the root password
being exposed in logs.

This PS adjusts the MariaDB chart to use the same endpoint values
layout as used in other openstack-helm components. It also removes
credentials and params from the configmaps and moves them to secrets
and env vars as appropriate.

Addresses consistency issues that appear with autoincrement fields in
the existing chart, as demonstrated in [1]. It should allow automatic
recovery of 2 out of the 3 (default) cluster members.
It does not address automatic recovery of a complete shutdown of all
cluster nodes.

Galera has a copule of options to sync mariadb cluster.
Default value is mysqldump which is slow, except for small data-sets, but is the most tested option.
rsync option is much faster than mysqldump on large data-sets.
So add --wsrep_sst_method value.

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.
