remove default value of repeat-actions

I94468ff649dd4367848c74e94a3feb08494bb223 fixes problem that ceilometeclient
incorrectly reset repeat-actions when update any attribute.

I53f3af447a8f814388985f6e4ab57a8ffec18a2a reverts most of the above change,
which leading to bug 1539092. Because repeat-actions has default value False,
no matter we set it or not, it will replace this bit when we get alarm from API.

The unit test doesn't cover such case, so this change still succeeds in CI test.

We don't need to revert it again, because the redundant code for create and update
is not needed, repeat-actions has default value (False) in API side, so the proper
way is simply removing the default value in CLI side.
