Several bundled updates
- The latest envoy docker containter was broken, made changes to request
  a sepcific commit version of the container known to work.
- A minor change to the proxy configuration file where the same name was
  used for 2 virtual_hosts.
- An update to CreateInstaller.sh for use in multi-user mode which tries
  to guess a the cord_home rather than having the user set it.
- A change to the swarm start script to wait for consul to establish the
  master before starting the remainder of the dependent containers.
