ssh command limits for toci virsh don't match ironic commands

[Robert Collins]

The testenv hosts run a command limited ssh environment - see elements/testenv-worker/bin/ci_commands in tripleo-ci - but this doesn't yet support ironic's ssh driver.

Looking at the ci_commands file what is failing is the regex on the commands. Ironic is setting the virsh "--connect" option where Nova BM is not. Also on ironic has a couple of additional spaces in the list --all command. I will put up a patch shortly that should modify the regex to allow for these differences.
