Description

Now that YARN has been put in to trunk we should do something similar to MAPREDUCE-849. We should go back and look at all of the configurations that have been added in and rename them as needed to be consistent and subdivided by component.

1. We should use all lowercase in the config names. e.g., we should use appsmanager instead of appsManager etc.
2. history server config names should be prefixed with mapreduce instead of yarn.
