[~vvasudev], branch-2 is already committed, forgot to update.
Do we want this in branch-2.8 ? 
Looks like there are quite some conflicts, and this is kinda a new feature

> Instead of the default random docker container hostname, we could set a more user-friendly
hostname for the container. The default could be a hostname based on the container ID, with
an option for the AM to provide a different hostname. In the case of the native services AM,
we could provide the hostname that would be created by the registry DNS server. Regardless
of whether or not registry DNS is enabled, this would be a more useful hostname for the docker
container.
