[feature] Support for Artifactory

[GeoffWilliams]

If only there were a way to make OS packages and puppet modules available locally.

Running a local artifactory server (on laptop or corporate) would give a nice speed boost and would also validate corporate modules are correctly published for those who must operate this way.

Integration points:

• R10k (host)
• yum config (container)
• apt config (container)
• chocolatey config (container)
