Rakesh Radhakrishnan updated HDDS-6200:
---------------------------------------
    Description: 
The idea here is to add {{OM#getSupportedLayouts()}} RPC call to get the bucket 
layout values. 

Before finalization {{OM#getSupportedLayouts()}} RPC call should return empty 
values. Now, new client's {{OzoneClientAdapter and CreateBucketHandler}} would 
get an empty [] list then continue with the existing older version behavior.

After finalization {{OM#getSupportedLayouts()}} RPC call will have values 
FSO/OBS and the client will have the new behavior.
