Ed Santiago 2e8c074234 CI: use local registry, part 1 of 3: setup ...

As of https://github.com/containers/automation_images/pull/357
our CI VMs include a local registry preloaded with all(*)
images used in tests.

 * where "all" means "most".

This commit installs a new registries.conf that redirects docker
and quay to the new local registry. The hope is that this will
reduce CI flakes.

Since tests change over time, and new tests may require new
images, this commit also adds a mechanism for pulling in
remote images at test run time. Obviously this negates
the purpose of the cache, since it introduces a flake
pain point. The idea is: DO NOT DO THIS UNLESS ABSOLUTELY
NECESSARY, and then, if we have to do this, hurry up and
spin new CI VMs that include the new image(s).
