Description: The JobTracker Instrumentation API is currently sending
JobTracker configuration to submitJob(conf, JobID) call. Instead, this should
be changed to submitJob(job.getJobConf(), JobID) to obtain job related
configuration. i.e., Chukwa could use this API to find out the job history
file location. In addition, the API should be public for general public to
implement useful utilities to interface with this API. (was: The JobTracker
