Test: client: start, stop, destroy: add tests for --glob/--all

Test the CLI client's start, stop, and destroy commands along with their
--all and --glob options.

The tests validate that only the targeted sessions are affected by the
various commands and that the commands don't error-out when multiple
sessions are targetted.
