Hi all
will instance action deprecate in feature since we have notify mechanism now?
Currently, nova have instance action and instance event action to record specify actions performed on a instances.
For some enterprise user, they may need to compute the latency when they perform an action on an instance.

I check instance action only record the start time but no finish time. Instance action event have start time and finish time. But for 1 instance action , there may be several instance action event, so there is no necessary to check all instance action event, we only care about the action time itself, so a finished time is necessary to added into instance action.

I made a patch to add finish time of instance action in [1](but need to fix unit test issue), I wonder if it is worthy to
Spend time on debug unit test issue? Since I remember that instance action will be deprecated soon.
