Review request for atlas and Suma Shivaprasad.


Bugs: ATLAS-503
    https://issues.apache.org/jira/browse/ATLAS-503


Repository: atlas


Description
-------

The patch implements retries in HBaseKeyColumnValueStore while acquiring locks within a JVM
using the LocalLockMediator. The number of retries is configured using atlas.graph.storage.lock.retries.
As described above, the value for this property should be equal to the desired level of parallelism.
For e.g. if this is set to 10, it means that 10 concurrent operations can proceed to acquire
locks on the same store, key and column.

Testing
-------

* Existing UTs and new UTs added here.
* Also set this configuration to 10 retries and verified that 10 concurrent users from JMeter
can create traits in parallel.


Thanks,
