[COOK-3945] & [COOK-3931] Add upstart script for Ubuntu 13.04/13.10

This might be a bit quick and dirty, however it fixed the problem for me when building an Ubuntu 13.04 box. The upstart script has been taken straight from the latest mysql-server package https://launchpad.net/ubuntu/raring/amd64/mysql-server/5.5.34-0ubuntu0.13.04.1 and https://launchpad.net/ubuntu/saucy/amd64/mysql-server/5.5.34-0ubuntu0.13.10.1
