rm -f now removes a paused container

We now can remove a paused container by sending it a kill signal while it
is paused.  We then unpause the container and it is immediately killed.

Also, reworked how the parallelWorker results are handled to provide a
more consistent approach to how each subcommand implements it. It also
fixes a bug where if one container errors, the error message is duplicated
when printed out.
