scripts: add wait script for watching run

While using teuthology-suite with --wait option it is
usefull sometimes to split the suite scheduling and
the run waiting. For example, when using tools like
Jenkins we might want to schedule a suite, report
about successful schedule and start waiting only in
the next steps.
