This commit aims to support the creation of the galera cluster via
Pacemaker. With this commit in, three use-cases will be supported.
* Non HA setup / Non Pacemaker setup : The deployment will take place
as it is currently the case in f20puppet-nonha. Nothing changes.
* Non HA setup / Pacemaker setup : Even though it is a non ha setup,
galera cluster via pacemaker will be deployed with a cluster nbr of 1.
* HA setup / Non Pacemaker setup : N/A
* HA setup / Pacemaker setup : It is assumed that HA setup will
always be with pacemaker. So in this situation pacemaker will deploy a
cluster of 3 galera master nodes.

This patch adds support for using the Heat resource registry
so that end users can enable pacemaker. Using this approach
allows us to isolate all of the pacemaker logic for the
controller in a single template rather than use conditionals
for every service that must support it.

Adds optional hooks which can run operator defined additional config on
nodes after the application deployment has completed.

The upcoming heat hook/breakpoint features will enable stepped deployments
via setting stop points via the resource_registry.
For this to work, we need hard dependencies between each step of the
puppet deployments, because the current "soft" dependencies caused by the
name property only influences the hook script application ordering, not
the graph traversed by heat during deployment.
Since removing the name: puppet_n completely removes some useful self-
documenting context, move this to a resource naming convention, which
should also be useful for heat hooks/breakpoints, as they are expected
to support globbed specification of each step.

The loadbalancer Puppet code moved to puppet-tripleo (lightweight)
composition layer.
This patch aims to use it and refactor the loadbalancer.pp file.

This patch adds a new ControllerNodesPostDeployment resource
which can be used along with the environment file to
specify a nested stack which is guaranteed to execute
after all the Controller config (HA, or other) have
executed.
This is really useful for Puppet in that Heat actually
controls where puppet executes in the deployment
process and we want to ensure puppet runs after
all hiera configuration data has be deployed to
the nodes. With the previous approach some of the
data would be there, but most of the HA data which
actually gets composed outside of the controller-puppet.yaml
nested stack would not be guaranteed to be there in time.
As os-apply-config (tripleo-image-elements) have their
ordering controlled within the elements themselves an empty stubbed
in nested stack has been added so that we don't break that
implementation.
