Title: add arbiter to percona playbook

This adds the arbiter task to the percona playbook which does the following:

* Installs the garbd binary via percona's galera pkg on the compute node
* Installs a garbd upstart script
* Configures garbd's gcomm URL within the upstart script so it will join the existing DB quorum on startup
