Revert "Added support for private projects."

This reverts commit r247456.  With that change in the CQ,
the Chromium CQ fails to start because it could not import
projects_internal.  It may be that the CQ checkout needed
updates to other source trees, but that clearly was not
happening and the CQ outage was disrupting Chromium devs.
