compute: Fix weird option definition for 'server ssh'

argparse allows you to specify multiple options for a given argument
when declaring the argument. For some reason, we weren't doing this for
the 'server ssh' command. There's no apparent reason for doing things
this way and it's been that way since the beginning (2013) so let's not
do that.

We also add unit tests since they were missing and should exist.
