------------------------------------------------------------------
Initial attempt at solution. Although I'm a little apprehensive to the
additions to cassandra.thrift
(describe_rack(..) isn't used anywhere, it just made sense to add
describe_datacenter(..) and describe_rack(..) at the same time).
I've tested that existing hadoop jobs work but the new functionality hasn't
been tested (as i currently don't have any RF=2 data setup).
This patch does not include the required re-generated Cassandra.java
