This provides a script to resync the hound configuration for
codesearch.
It checks if the config needs updating, and if so, puts the new config
file in place, takes the reindex lock from
I9d28201bca75b624e07cbba14c870151094fc7ae and restarts the service,
waiting until it sees it is up.
puppet is currently disabled on this host because updates are tied to
project-config changes; since restarting takes the service down this
is obviously not great.
