      Description

      Interop testing is broken after landing "LU-11025 dne: introduce new directory hash type: "crush"".

      It makes impossible to start new client that include 0a1cf8da8 with servers that don't:

      cslmo1103: error: set_param: param_path 'lod/*/mdt_hash': No such file or directory
      pdsh@c-lmo004: cslmo1103: ssh exited with exit code 2 

      I guess following code should check that MDTs support mdt_hash param:

      init_param_vars () {
      ...
              do_nodes $(comma_list $(mdts_nodes)) \
                      "$LCTL set_param lod.*.mdt_hash=crush"
              return 0
      }
