Description of problem:
When deprovisioning a BMH, using the kebab menu->deprovision, no feedback is provided to the user that the action actually started, and no events are registered in the recent activity card.

Version-Release number of selected component (if applicable):
4.8-0-fc9

How reproducible:
100%

Steps to Reproduce:
1. From the nodes page, mark one of the workers unschedulable
2. From the bare metal hosts page, make sure you locate the same worker (the name of the BMH and the name of the node are not necessarily consistant), and choose "deprovision" from the kebab menu
3. It is not clear if something happened or not, so open the details page of the BMH and look in the events

Actual results:
No events. You just have to be patient until you see the host deprovisioned.
