OpenCraft IM - Terminate VMs on instances linked to a closed/merged PR

gistfile1.py

# Ensure to disable auto-indent before pasting in ipython: %autoindent
# TODO: Disable monitoring
# TODO: Hide from UX (archive)
from pr_watch import github

for instance in OpenEdXInstance.objects.filter(watchedpullrequest__isnull=False):
    pr = github.get_object_from_url('https://api.github.com/repos/{}/pulls/{}'.format(
      instance.watchedpullrequest.target_fork_name,
      instance.watchedpullrequest.github_pr_number
    ))
    if pr['state'] == 'closed':
      for appserver in instance.appserver_set.all():
        appserver.terminate_vm()

@antoviaque: does it also make sense to delete the instance itself?

@e-kolpakov We should probably find a way to hide it from the UX (archiving?) when it doesn't have any active appserver anymore, but for record-keeping purposes we probably don't want to delete the objects themselves.
