Upgrade groups portal instances to use manifest based deployment

Both staging and productive groups instances will use the manifest
published at tarballs.openstack.org/groups/drupal-updates catalog.
It helps to separate the staging and prod deployment source
versions, passed in package_branch parameter. Drush dsd tool updated
to v0.9, and puppet sitedeploy and siteupdate resources were also
refactored to support drush-dl package provider parameters.
