Geo-redundant HA deployment without Layer 2 Networking

To deploy Geo-redundant HA without Layer 2 Networking:
  1. Fresh deploy all Routing Core Server services except AE Services on both data centers.
  2. After the Routing Core Server services are up, deploy AE Services.
Fresh deploy mega-config.yml for data center 1
# User with password less ssh and sudo access
# for the whole cluster
