Bug description:
The notification sample test for unshelve waits for the instance to
reach ACTIVE state and then asserts if unshelve.end notification is
emitted properly. However the instance.vm_state is set to ACTIVE
earlier[1] than emitting the unshelve.end notification[2]. This can
cause two different test case failures.
1) _test_unshelve_server() fails with no ushelve.end notification
received.
2) _test_shelve_and_shelve_offload_server() also has a unshelve action
at the end and that test step also only waits for the the ACTIVE
state. So the unshelve.end notification from the end of
_test_shelve_and_shelve_offload_server() can bleed into the
_test_unshelve_server() step causing that it receive one more
notifications.
