##### SUMMARY
<!--- Explain the problem briefly below -->
There were some changes in the RHV engine which changed sys_vendor. So now the setup facts are not correct.
(https://bugzilla.redhat.com/show_bug.cgi?id=1904085)

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
setup - virtualization facts
##### ANSIBLE VERSION
<!--- Paste verbatim output from "ansible --version" between quotes -->
```paste below
ansible 2.9.15
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/mnecas/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.6.8 (default, Apr 16 2020, 01:36:27) [GCC 8.3.1 20191121 (Red Hat 8.3.1-5)]
```

##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->
You need to have RHV 4.4.3 and some VM inside on which you will run:
`ansible -m setup host -k -u root | grep virtualization`


##### EXPECTED RESULTS
<!--- Describe what you expected to happen when running the steps above -->
`ansible -m setup host -k -u root | grep virtualization`
```
        "ansible_virtualization_role": "guest",
        "ansible_virtualization_type": "RHV",
```

##### ACTUAL RESULTS
<!--- Describe what actually happened. If possible run with extra verbosity (-vvvv) -->

<!--- Paste verbatim command output between quotes -->
```
        "ansible_virtualization_role": "NA",
        "ansible_virtualization_type": "NA",
```
