Ben Nemec 58d6c6478a Add unit test for cache-url
A sanity check that cache-url does the right thing when presented
with the appropriate curl return codes.  This change brings in the
test code for scripts from tripleo-image-elements, which needs to
be factored out into a place both projects can use it.

I'm stubbing out curl so we don't have a dep on curl in our unit
tests, and because I've seen some strange behavior out of curl in
the gate that caused random failures in this test.
