Review request for hive.
Bugs: HIVE-10927
https://issues.apache.org/jira/browse/HIVE-10927
Repository: hive-git
Description
-------
Adds following new metrics to HMS, can be renamed if necessary.
"open_connections"; //#HMS clients connecting to HMS
"active_jdo_transactions"; //#active JDO transactions
"rollbacked_jdo_transactions"; //#failed JDO transactions
"committed_jdo_transactions"; //#successful JDO transactions
"opened_jdo_transactions"; //#attempted JDO transactions
Also to HS2:
"open_connections"; //#HMS clients connecting to HMS
This also fixes some minor issues:
1. For the metrics JSON-file-reporter, the file system was not chosen right.
Fixing that, and also making the default the local file system.
2. The metrics was getting closed in the metastore in the wrong place, fixing
it.

Adding some unit tests, and tested manually for HS2 which cannot be unit-tested.
