Title: Add `app.rolling_stop_start` task

This is a task which forcibly executes in serial mode only and stops/starts a named app. It will exit on the first failure to execute instead of warning.

One thing I couldn't figure out is the right command to get the script to block until the server is running - given the way we use Unicorn herder and parent processes I'm not sure this is even possible.
