[tor-commits] [stem/master] Support multiple '--test' arguments

[atagar@xxxxxxxxxxxxxx]

commit 99e5ac8220f6d50018191a4a76b5f30522519f9b
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>

    Support multiple '--test' arguments
    
    When supplied our '--test' argument limits us to only running that specific
    test. I added this to help with single-test troubleshooting, but on reflection
    it could be useful to the network team as well to limit their CI to only run
    the tests they're concerned with.
    
    Only gotcha was that we didn't support multiple '--test' arguments. Resolving
    that.
