Add loadbalancer profile for ha & non-ha
The profile contains Puppet classes to deploy loadbalancer services (HAproxy & Keepalived) for ha & non-ha scenarios. A future iteration will split HAproxy & keepalived, but for now, we just want to move out the code from THT to puppet-tripleo. Change-Id: I9b106dcc1a4d446ab5dea8430ed295e6ec209cbd Implements: blueprint refactor-puppet-manifests
