   ## What changes were proposed in this pull request?
   
   BucketEndpoint#multiDelete deletes keys one by one. This causes 2 problems:
   1. **Bad performance**: To delete each key, a round trip to the OM is made.
   2. **DIRECTORY_NOT_EMPTY errors**, due to deletion order (in FSO buckets): 
For FSO buckets, if the directory is mentioned before the keys(inside the 
directory) in the multidelete request, it causes the request to fail even 
though it should be successful.
   
   By reimplementing multidelete using OMKeysDeleteRequest to delete all items 
in a batch, these problems can be resolved. 
   With the existing API deleteKeys, we would not be able to get a list of 
errors for the keys that could not be deleted. Moreover, a OMException was 
being thrown if any errors were encountered.
   In this PR, a new API is introduced deleteKeysQuiet to tackle these changes 
while maintaining compatibility.
