Bug 1619618

Description of problem:
If you go to SSUI -> My Services -> <some_service>, there is Resources section. It displays VMs and (among other things) their power state. It might happen that the power state is displayed as unknown while the actual VM is in reality started. That is a problem because it means you cannot stop it from SSUI. The option Stop in Power Operations button on the service view is disabled. And there is no way how to refresh the VM's power state from within SSUI.

Version-Release number of selected component (if applicable):
5.9.4.4

How reproducible:
? 
I am not really sure how to reliably get to the state where power state of VM in SSUI is unknown. I think it might be caused by suer going to check VM in SSUI very quickly after it's provisioned, but I am not sure about it.

Steps to Reproduce:
In Admin UI:
1. Create a Service Dialog
1.1 Go to Automation -> Automate -> Customization -> Service Dialogs -> Configuration -> Add a New Dialog
1.2 Set Dialog's name (my_dialog). Add some element, e.g. Text Box.
2. Create a Service Catalog
2.1 Go to Services -> Catalogs -> Catalogs -> Configuration -> Add a New Catalog
2.2 Set Catalog's name (my_catalog) and click Add
3. Create Catalog Item
3.1 Go to Services -> Catalogs -> Catalog Items -> Add a New Catalog Item
3.2 Choose Catalog Item Type. In my case, I was using Red Hat Virtualization.
3.3 Set Catalog Item's name (my_catalog_item)
3.4 Set Display in Catalog to True
3.5 Set Catalog to my_catalog
3.6 Set Dialog to my_dialog
3.7 Fill in the Request Info tab. I did it in a way that the new VM was provisioned as a Native Clone from template. Make sure that VM is scheduled to start after provision. In the end, click Add.
4. Go to Services -> Catalogs -> Service Catalogs -> my_catalog -> my_catalog_item and click Order. Fill in something into Text Box and click Submit.
5. Wait for your provisioning request to finish.
In Self Service UI:
6. Go to My Services -> <your new service>
7. Check Resources section

Actual results:
From time to time (but still quite rarely) it happens that your newly provisioned VM has power state unknown in Resources section. Unfortunately, I don't know how to get to this state reliably. I discovered this while running test_service_start test case from integration_tests framework. Out of 10 executions, the unknown power state has been encountered twice. Anyway, unknown power state isn't the problem, the problem is that it cannot be refreshed from SSUI.

Expected results:
I'd like to have an option to refresh power state of VM from UI. Because if I am a consumer of service that does not have an access to the admin UI, I am stuck with this.

Additional info:
- Workaround: If you find your VM in admin UI and do Configuration -> Refresh Relationships and Power states, the power state is refreshed even in SSUI. However, this can only be applied if you actually have an access to admin UI.
- I have attached engine.log from RHV engine and also logs from appliance. If you want to search for a VM that led me to discovery of this bug, search for:
VM: test-serv--ocam0001
Catalog Item: 3O2sWWsWbj
Catalog: cat_BlWjNdYqHJ
- I have also attached some screenshots from admin and SSUI
