-- Returns information about the upload buffer of a gateway. This operation
-- is supported for the stored volume, cached volume, and tape gateway
-- types.
--
-- The response includes disk IDs that are configured as upload buffer
-- space, and it includes the amount of upload buffer space allocated and
-- used.
