Disable docker hub mirror use in jobs

Browse Source 
Docker hub rate limits have become a problem made worse by forcing all
of our requests through a single IP per cloud region (the docker hub
proxy cache running on our mirror nodes). Attempt to alleviate these
issues by disabling the use of the proxy cache for docker hub. This will
allow us to use far more IPs which should make this less of an issue. Of
course that will create more network traffic which isn't ideal either
and we may be more susceptible to network problems.

We do this by configuring an empty zuul_site_mirror_info which the
depends on looks at and will noop if present without a dockerhub config
in this dictionary.
