[ENHANCEMENT] Allow bastille to run commands on multiple jails in parallel instead of one after the other (serial).

[yancyb-ehit]

Currently when running bastille, it only runs on one jail at a time. It would be nice if I could get them to run in parallel. This could greatly speed up some operations.

A switch with a number might work. The number being the number of jails ran in parallel. Default being 1, so current behavior is maintained.

I suppose I could call bastille in some kind of xorg or script per host and run it in parallel that way. I would think a switch or something similar so consistency is maintained would be better.

not sure this is really an option. In the past when this was discussed, we have no way in a bash shell to spin up parallel processes. IF I am wrong on this, or someone has an idea of how to do it in parallel please jump in and correct me.

I wonder if the exec command will do that since it libertares the process, but have to check it. Anyway will not be exactly a parallel process.

Also don't forge &, like command1 & command2. That said, @yancyb-ehit have you tried something like bastille command target & bastille other-command target ?
