Review comment:
       It's because ```ITTestDynamoDBBasedLockProvider``` is located under 
```hudi-client```, ```TestZookeeperBasedLockProvider``` is also located under 
```hudi-client```. Do you want me to relocate it to ```hudi-integ-test```?

Review comment:
       > If lock is not granted, why do we throw exception here? LockManager 
has a retry mechanism through which it will try to acquire lock few times with 
some delays inbetween. Don't think we can throw from here if lock could not be 
acquired.
   
   If we don't catch ```LockNotGrantedException```, then ```LockManager``` also 
won't catch this exception: 
https://github.com/apache/hudi/blob/master/hudi-client/hudi-client-common/src/main/java/org/apache/hudi/client/transaction/lock/LockManager.java#L75,
 then the whole program would crush w/o retry logic.

also won't catch this exception:
