Missing slash in /v1/strategies{strategy_uuid}/state path

[Alexandra Nyitraiova]

I was trying to issue a command `watcher strategy state wm_workload_conslidation --debug` and it responded with 500 response status. I think, the problem may be, that a slash is missing on the following line and therefore none of the routes is matched:

https://opendev.org/openstack/watcher/src/branch/master/watcher/common/policies/strategy.py#L59

The strategy is vm_workload_consolidation, not wm_workload_conslidation

It's ok for my testing.

watcher strategy state vm_workload_consolidation

I tested this in devstack and for me it also seems to work. I would have expected there to be a slash in that path though.

Could you test if executing: `watcher strategy state vm_workload_consolidation` works for you?

[Alexandra Nyitraiova (saskan)]

I am sorry, that was just a typo. In my console, I copied the name of the strategy from list `watcher strategy list`, therefore I am sure I have the command right.

Could you paste the log for watcher api?

[Alexandra Nyitraiova (saskan)]

Sure. Here it is. (I have OpenStack deployed through Kolla)
