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.
Can these recipe includes instead be in a role should someone want Java this way? (Particularly, `bcpc-hadoop` should not be a dependency of the `hannibal` cookbook.)
