…/docker roles by using packages from contrail-install-package package.
In the docker role, if install_method is package, use the specified
contrail_apt_repo apt repository to install docker-engine(or specified) package.
In the node role, do not use "pip" module to get doker-py but use the
corresponding package in the official ubuntu repo - python-docker.
Unfortunately the dependencies for python-docker has not been captured
correctly in the deb specs. Have to manually install a few missed out
dependencies like python-ipaddr and python-urllib3
In site.yml, afte compute node is rebooted, wait for a specific port rather
than just wait for timeout.
