class_docstr: BytePS backend for MXNet KVStore interface.
docstr: Queries if the KVStore type supports certain capability, such as optimizer algorithm,
  gradient compression, sparsity, etc.
  As byteps server does not store weight, this function will return false for any capabilities.
  
  Parameters
  ----------
  capability: str
      The capability to query
  
  Returns
  -------
  result : bool
      Whether the capability is supported or not.
