Bugs: HIVE-7445
https://issues.apache.org/jira/browse/HIVE-7445
Repository: hive-git
Description
-------
This patch enables ZookeeperHiveLockManager.java, when in debug mode, to log
out information about contentious locks if lockmgr fails to acquire a lock for
a query. The changes include:
1. Collect and log out contentious lock information in
ZookeeperHiveLockManager.java
2. Improve lock retry counting and existing logging, and modified some qtests
output files to match these logging

Testing
-------
1. Manual tests: following debug logging was printed out as expected during a
lock acquisition failure.

2. Precommit tests
The test failure testCliDriver_ql_rewrite_gbtoidx is a preexisting one and I
think it is not related to this change.
