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 failure.
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.
So this patch adds an extra
self._wait_for_notification('instance.unshelve.end') call to each test
step to prevent the instability.

Stabilize unshelve notification sample tests
