[STORM-3271] Docker support: launch storm workers in docker containers
Spent a lot of effort on this.
This patch let storm supervisor launches the worker in a docker container
so that user code is isolated from each other and from the host machine. This
is a security enhancement.
Detailed explanation of this are available at docs/Docker-support.md in
this pr.
I tested it manually (only on `RHEL7`, didn't test it on other os systems)
and tested with secure cluster setup. Also tested with our own integration test
suites with docker support turned off and proved that this pr won't break storm.
