Remaps a per-node return list into an a per-provider per-node dictionary

Parameters
rlista map with node uuids as keys and ExtStorage objects as values
Returns
dict

a dictionary with extstorage providers as keys and as value another map, with node uuids as keys and tuples of (path, status, diagnose, parameters) as values, eg:

  {"provider1": {"node_uuid1": [(/usr/lib/..., True, "", [])]
                 "node_uuid2": [(/srv/..., False, "missing file")]
