Support for Ocata-Pike live-migration over ssh
In Ocata all live-migration over ssh is performed on the default ssh port (22). In Pike the containerized live-migration over ssh is on port 2022 as the docker host's sshd is using port 22. To allow live migration during upgrade we need to temporarily pin the Pike computes to port 22 and in the final converge we can switch over to port 2022. This also changes the default port to 2022 for baremetal computes in Pike to enable live-migration between baremetal and containerized computes.
