Alex Schultz c6918e5da6 Migrate install to deploy-guide 
The deployment guide is currently pointed at triplo-docs but it has been
requested that we actually publish a deployment guide. This change
extracts many of the installation doc pages and moves them into the
deploy-guide source tree.  Once the deploy-guide is published, we will
follow up to reference the deployment guide from tripleo-docs.

Configuring High Availability

supports high availability of the controller services using Pacemaker. To enable this feature, you need at least three controller nodes, enable Pacemaker as the resource manager and specify an NTP server.

Create the following environment file:

$ cat ~/environment.yaml
parameter_defaults:
  ControllerCount: 3

And add the following arguments to your openstack overcloud deploy command to deploy with HA:

-e environment.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/docker-ha.yaml --ntp-server pool.ntp.org
