Update standard puppet modules to new mysql and add cloudera

This updates all the modules in use for new mysql puppet module.
Includes porting install_modules feature from openstack-infra
to install puppet modules from git URL. We use this to pull
in a forked version of puppet-dashboard. The forked version
was necessary to also make it compatible with new mysql module.

All of the mysql updates allows us to use the cloudera module.
