Implement Xenial Support

Browse Source 
This commit implements support for Ubuntu 16.04 Xenial.  Changes
include renaming several variables from galera_* to percona_* for
clarity.  The reason for this change is that 16.04 will be using
distribution provided packages for percona-xtrabackup.

Mariadb 10.0 packages are available for Ubuntu 16.04, so those
packages and installations procedures will remain unchanged.
