Description of problem:
The engine allows adding a new host using IP as hostname while the host already exists and appears with FQDN

Version-Release number of selected component (if applicable):
vdsm-4.40.0-1468.gitec7d91cc0.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Install hosted-engine
2. Via the GUI add a new host with a different name and use the hosted-engine IP address as hostname

Actual results:
The same host appears twice

Expected results:
An explicit error when trying to add the same host

Additional info:
There is no option to remove such host it gets stuck in "PreparingForMaintenance" status
Comment 1 Nikolai Sednev 2020-03-31 13:28:43 UTC 
Forth to our discussion with Asaf, I added a new host with a different name and used the existing ha-host's IP address as Hostname/IP for the new host.
Engine refused as expected with:
"Error while executing action: Cannot add Host. Host with the same UUID already exists.
Close"

Tested on host with these components:
