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.
The evolutions templates are required for changing the schema and queries to MYSQL mode. They need to be run after install hannibal and before starting hannibal. So doing it in a wrapper becomes difficult.
We could set default schema mode even for H2 to MYSQL and use these templates always.
