Remove implicit iteration from Crosstool

Up until now we allowed implicit iteration, e.g.:

flag_group { flag: '%{some_sequence_variable}' }

From now on, snippet above will raise an error. We require explicit
'iterate_over' message, e.g.:

flag_group {
  iterate_over: 'some_sequence_variable'
  flag: '%{some_sequence_variable}'
}

RELNOTES: Implicit iteration in the CROSSTOOL has been removed, use explicit 'iterate_over' message.
