sneakernet_ca requires a newer certmonger not hosted publicly.

For a few nights since c106830031e5e17c43fc84f862e3b0bb5a29c882, nightly builds were failing with an dependency error in the installer:

So, yesterday @jvlcek @kbrock and I packaged the [sneakernet_ca in copr](http://copr-be.cloud.fedoraproject.org/results/jrafanie/manageiq-scl/epel-6-x86_64/).

Then, it failed again, with a different error.  The imagefactory screenshot shows this:

After doing an OS-only appliance build, yum install indicated the real error:

Error: Package: sneakernet_ca-0.1-2.el6.noarch (jrafanie-manageiq-scl)
           Requires: certmonger >= 0.75.8
           Installing: certmonger-0.61-3.el6.x86_64 (base)
               certmonger = 0.61-3.el6

Once this is available publicly, we can re-add sneakernet_ca.
