Jose Luis Franco Arza 11ff6d0668 Add extra yaml validations in upgrade tasks.
Extra checks:
 - Check that only tags=['common', 'validate',
  'pre-upgrade'] are accepted.
 - Fail if tags not defined.
 - Fail if 'step|int == ' condition inside 'when'
   is not the evaluated first.
 - Suggest the use of lists to append conditions
   inside 'when'.
