For this jira, you are proposing to have an implementation in OM which takes 
the username, and returns the Volume for that user if it exists or else return 
"NO VOLUME for User" (where can map this to just return empty response). Let me 
know if my understanding is correct.

> Implement s3 bucket list backend call and use it from rest endpoint

> HDDS-657 provides a very basic functionality for list buckets. There are two 
> problems there:
>  # It repeats the username -> volume name mapping convention.
>  # Doesn't work if volume doesn't exist (no s3 buckets created, yet).
> The proper solution is to do the same on server side:
>  # Use the existing naming convention in OM
>  # Return empty list in case of value is missing.
> It requires an additional rpc call to the om.
