The output of cluv submit first is not very pretty. It prints the commands for each cluster using something like console.print, but we could/should display that information in a table instead!

Same for the job ids for each cluster (or "error" if we were unable to submit a job there). It could/should be a nice, rich.Table of some sort. This would make the output much nicer and clearer to look at.

The information on how to watch the progress of the job that did end up running should also be at the end of the message, after the table.
