Start MapReduce History Server
This PR starts the MapReduce History Server and opens ports on master
It should fix tests in this PR in skein https://github.com/jcrist/skein/pull/197
As htcluster command seems to pull docker image. I didn't know how to easily test with the docker image built from source. So I did the test by starting by hand the MR history server (using htcluster -u root -s master exec -- mapred historyserver
)
