Gregory Haynes e5e46a69df Make wait_for use getopt and add walltime support
We currently use wait_for which does not account for time spent blocking
during COMMAND. This leads to issues where it is hard to calculate time
we want to spend waiting for something. Modifying wait_for and
wait_for_stack_ready to support walltime based timeouts.
