Apply artifact-id updates to version checks in master

SERVER-518 covers some updates around the package 'group-id' and 'artifact-id' that Puppet Server uses with respect to calls to the version check service. The big changes were around changing the 'group-id' from "puppetlabs.packages" to "puppetlabs" and the 'artifact-id' from "puppet-server" to "puppetserver".

The nature of the changes on the Puppet Server master branch will be a little different than those on the stable branch because of the work which was done on the master branch to move from the embedded version check service to the separate dujour.version-check library.
