Foreman » Smart Proxy

Note that as per https://github.com/theforeman/foreman/pull/2517, we only have Ruby 2.2.1 available via rvm on our Jenkins infra rather than any later patch level. Hopefully it'll work for the proxy, if not Foreman.

https://github.com/theforeman/foreman-infra/pull/192 added 2.2.3 to the smart proxy develop test matrix, which now fails with:
