Description of problem:
[4.5] [UI] BMH Actions / ‘Power Off’ still seen during phased reboot when host is already powered off with annotation


How reproducible:
100%

Steps to Reproduce:
1. Deploy cluster OCP 4.5
2. Login UI console and select Compute -> Bare Metal Host
3. Click on worker node <openshift-worker-0-0>
4. Click under actions/ edit annotation
5. Click add more and you will have ability to add KEY and VALUE
6. Add "reboot.metal3.io/anydata" in KEY only.  Note:  anydata can be any string

7.  This invokes the BMO Reboot "Phased Reboot".  Phased Reboot will bring host down
and remain down until the annotation is deleted from host.

Actual results:

After we see the host go down, I check on the very right
Compute->BMH-> 3 dots and still found "Power Off" in the drop down list.
This relates to https://bugzilla.redhat.com/show_bug.cgi?id=1844238
My best guess is it would have "Power On" if above bug is resolved 

Expected results:
This bug should address "phased" reboot feature.  I would think we would
not want either "Power Off or Power On" available.  Perhaps can be either
removed or tied directly to a new button but either way the workflow is broken IMO.
