support proposed flag changes of peridodicnoise

periodicnoise will switch to a new flag package which make it more easy
to extend it, supports common unix like option semantics and provides a
awesome help.

All users of this puppet module will see no changes as all options are
abstracted away.
need at least version 0.5 for new changes.
