RFE: verify specific sequence of monitoring events

Hi Sridhar, we need to add timestamp to check the event sequence in the below function

https://github.com/openstack/tacker/blob/master/tacker/tests/functional/base.py#L133

right ?

when i sort the timestamp against resource_state, I am getting following o/ps ( some portion of actual output)

2016-09-09 11:44:34 ACTIVE
2016-09-09 11:46:01 DEAD

I have few doubts,
The flow should be PENDING_CREATE --> ACTIVE --> PENDING_DELETE --> DEAD
I could see following state in timestamp that PENDING_DELETE followed by PENDING_CREATE, there is No DEAD state in between
