Merge pull request #2 from TJM/master

Changes we collaborated on past 1am
Cosmetic, stage changes

Changed dependency between the ‘file’ and ‘gpg_key’ resources from
require to arrows.
Added a run stage to the Exec, making it run during spacewalk-setup.
Added parameters to epph::db

added $pw_one and $pw_two for the the 2 database passwords to get them
out of the code and into Hiera.
Reverted stage

looks like that didn’t work… ;)
Added explicit dependencies and an anchor class

The dependencies tie the resources together.  The anchor class ties the
resources together with the class itself, ensuring that it evaluates
when the class itself is evaluated in the parent scope.
