Description of problem:
Navigating to the main page of RHV-M presents you with a link to the API documentation. This link opens a API v3 version documentation. The API v4 documentation is missing

Version-Release number of selected component (if applicable):
RHV 4

How reproducible:
always

Steps to Reproduce:
1. Navigate to https://[URL of RHV-M]
2. Click on REST API Guide (left column Technical Reference)
3. Check the documented version of the API

Actual results:
 Version 4 of the Red Hat Virtualization Manager supports versions 3 and 4 of the Representational State Transfer API. The information and examples in this guide apply to version 3 of the REST API. 


Expected results:
AS we have v4 API available, I would expect a API v4 documentation at this point.


Additional info:
As a start there is already the model of the API documented:
