"""Validate and add a new item to the Invirt build queue.

This script, intended to be invoked by remctl, first validates the
build submitted parameters, and then adds a new item to the
Invirtibuilder build queue, triggering the Invirtibuilder to start the
build.

The expected arguments are

  pocket package commit

This script will also automatically extract the Kerberos principal
used to submit the job, and include that in the queue file for records
keeping.
