This change updates the list of playbooks to install via the AIO heat
templates. I have also removed the version number of the heat template
filenames.
Add Swift MaaS healthchecks.

* Add Check for local swift-proxy-server
* Add Check for local swift-container-server
* Add Check for local swift-object-server
* Add Check for local swift-account-server

Add galera alarms for https://github.com/rcbops/ansible-lxc-rpc/issues/403
Alarms for galera including @BjoernT improvements
Change maas_notification_plan to npManaged

When set to npTechnicalContactEmail for customers without a cloud
account, alarm creation will fail with an "Unable to create Alarm due to issues with account contact information. Please contact support"
error. Changing to npManaged allows alert creation to complete so alarm
tickets can be created.

Monitor changes

This change brings the monitoring playbooks/roles in line w/ how
everything else gets deployed by leveraging pre-existing roles for
repo configuration, software installation, etc.  We also split out the
agent and cli more so that the roles can be applied independently of
one-another.

Closes issue #255
Use root pass for galera init script

The galera init script uses the debian-sys-maint account to shutdown
mysql. However this password cannot be preseeded, and is randomly
generated on install. Also it is set in the database so must be updated
when replication has been achieved.

This patch implements an alternative: Use the mysql root password for
init script operations (shutdown). This password is preseedable and will
work at any state of replication.

This is no less secure than previous state as we already write root galera
credentials to /root/.my.cnf (0600) and /etc/mysql/debian.cnf is also 0600.

Use local socket for mysql client connection

This affects mysql client as well as mysqladmin, which is used in status
checks in the init script. It is important that the init script can
succeed regardless of LB state. (Prior to this commit, LB IP was used as
the host to connect to).

Use local socket for mysql client connection
Specialize galera client config

For reliable operation, the mysql client configuration must point to the
local instance, within galera containers. However this prevents the
mysql client from working on other constainers (eg utility).

This patch defaults the mysql connection to the VIP, then overrides that
to 127.0.0.1 for galera containers.
