Correctly set CombinationAlarm repeat_actions

Previously, the value of the repeat_actions property has no effect on
combination alarm creation, so this attribute defaulted to false on the
Ceilometer side, breaking Heat autoscaling.

Now, this attribute is set correctly as a top-level attribute on the
alarm.
