Remove a buggy method in sqlalchemy.api

watch_data_delete tries to retrieve session object from a result set instead of
managed objects. Further, from the name of the method, the intention seems to
remove watch data associated with a given watch rule, but it would actually
remove all watch_rules having the given watch_name. Though it would not succeed,
if there is any associated watch data.

Since this method is not referenced anywhere in the entire project, it might be
better to just remove it for now.

Remove spurious traceback in test

One of the engine_service test displays a traceback for no good reason
in the tests. Cleaning up the stack created in the tests removes it.

Make Autoscaling update policy tests faster

The tests for the update policy implementation in autoscaling and
instance group were relying on wallclock time, making them unusually
slow. This patch improves the situation a bit by stubing time calls.
