This type of task translates to an rt-app phase containing a 'run' event and a 'barrier' event, the name of the barrier being provided as a constructor argument. Implementing this requires some internal changes to the rta module: - The Phase class gains a barrier_after attribute. Since this is optional, the class now inherits from object instead of using a namedtuple. - The Phase objects' 'period_ms' field can now be None - it is now only accessed where it is required. - The task_phase object constructed in _confProfile, which now contains a 'barrier' field, is now order-sensitive, i.e. the 'barrier' field must come after the 'run' field. To preserve this ordering, we need to remove the 'sort_keys=True' from the json.dump call, which in turn requires that the entire phases object by converted to an OrderedDict.

Allows a synthetic which runs a set amount of time and then waits on a barrier. To be used for an extension of the heavy_load test that can simulate certain benchmarks.
