Review request for giraph.


Longer description available at the JIRA site. Short version: cleans up and refactors GraphMapper.
Begins a multistage process of setting up the underlying cluster framework (MRv1, MRv2 + YARN,
pure YARN, other cluster management platform...) to be decoupled from Giraph's BSP business
logic. After this patch, the main connection to Hadoop left in the processing code is the
Mapper#Context, and the various references it publishes into Giraph from Hadoop. Later JIRAs
will include more interfaces and a cleaner decoupling. Again, see the JIRA for more details.
