Provide Hannibal region monitoring service for hadoop cluster

1. This pull request provides hannibal cookbook.
2. There are two recipes: one to build hannibal tarball from source(hannibal_build) and other to configure,install and start hannibal as an upstart service (hannibal_hbase).
3. Mysql db, if selected, is configured for hannibal.
For reference, today only `active` is supported correct?
