Summary
-------
Make provision to report the AM hostname of an application in the RM/JHS UI.
It is difficult to trace back the AM on which an app ran when there are 100+
jobs in history. Digging through the logs is an option but since there is no
consistency maintained in naming of apps in UI/logs/local dirs
(MAPREDUCE-2793), debugging is all the more harder.
------------------
The big idea is to add the application master to the jobhistory ui so that can
be sort and increase search capabilities. Currently, adding anything to the
jobhistory apps page means to add to the job history file name since that is
parsed to get job meta data. This is done for performance reasons to prevent
reading all jobhistory files.
This addresses bug MAPREDUCE-3309.

Testing
-------
Manual test done:
1. Verify correct application master on job history apps page with jobhistory
files using new format
2. Verify old job history files are still usable to retrieve meta data minus
the application master
3. Verify all fields are searchable using field search as well and general
search
