When deploying check if there is already a container with the existing name. If there is rename it to "<version>_<random_hex_string>" to remove the name clash with the new container we want to boot. We can then do the normal zero downtime run/wait/stop. While implementing this I discovered the --filter name=foo does a substring match for foo, so I've updated those filters to do an exact match instead.
