Update eplite module for new version of eplite.

Etherpad lite has changed their source tree slightly. This has
required a few updates to the etherpad lite puppet module. The
custom pad.js needs to go in a different directory and the upstart
conf file needs a couple updated paths.

In addition to the fixes a couple things have been cleaned up. Now
define an etherpadlite.openstack.org node in site.pp and copy SSL
certs from /root/secret-files.
