/*
If docker.io is not responding to requests in a timely manner, this test suite will be adversely affected.

If you suspect such a situation, attempt pulling some openshift images other than ruby-22-centos7 or origin-custom-docker-builder
while this test is running and compare results.  Restarting your docker daemon, assuming you can ping docker.io quickly, could
be a quick fix.

Also, in order to build the test case specific builder images only once, we currently have to do all the testing within a single g.It block.
The project/namespace were being destroyed between tests, and that includes removal of the specific builder images
we built.  The credentials also are recycled between those points.

Dumping of the ImageStreams and Secrets JSON output at the various points proved this out.
