Direct package

[GeoffWilliams]

Hi There,

Thanks for your hard work on this package. I've developed a PR you may be interested in which adds support for directly downloading the RPM package from a regular HTTP server.

This is useful for places that both don't have their own yum repository or access to download from the Internet.

The PR works by adding a new parameter to the jenkins class called direct_download which the user can use to specify the whole remote path to the package file which can then be downloaded and installed.

I've also fully documented this, added an RSpec test class, added this new class into the anchors your using and fixed the metadata.json file (there were invalid version numbers and I'm using nanlui/staging to download remote files).

Hope this can be merged if at all possible.

Thanks,
Geoff
