Add HTTPS configuration option

[otteydw]

I've noticed in the latest epel-release RPM, they default to using HTTPS URLs. However the files installed by this Puppet module default to non-SSL URLs. I'd recommend adding an option for HTTPS urls.

hmm, I guess that has changed. Ok, when I do the next batch of fixes, I'll put it in.

It looks like the mirrorlist links are https on EPEL6 and 7. On EL5, everything is still http.

After checking for functionality, it looks like https work everywhere. I'll default to that.

As a small addendum to this, it looks like they're also using metalinks instead of plain mirrorlists. The relevant bits from the latest epel-release-6-8:
