Bug 2044034

The issue is that ansible-core-2.12 is installed and it provides an ansible version RHV currently doesn't support (ovirt-engine and ovirt-hosted-engine-setup require ansible-2.9).
This should fix that - https://github.com/oVirt/ovirt-hosted-engine-setup/pull/18

This bug was found, while trying to deploy on RHEL6.
Linux serval14.lab.eng.tlv2.redhat.com 4.18.0-359.el8.x86_64 #1 SMP Mon Jan 10 15:32:06 EST 2022 x86_64 x86_64 x86_64 GNU/Linux

When I retested on 
Red Hat Enterprise Linux release 8.5 (Ootpa)
Linux 4.18.0-348.el8.x86_64 #1 SMP Mon Oct 4 12:17:22 EDT 2021 x86_64 x86_64 x86_64 GNU/Linux
# yum list | grep ovirt-hosted-engine-setup ovirt-hosted-engine-setup.noarch 2.6.0-1.el8 rhv-4.5.0-1 
ovirt-hosted-engine-setup-2.6.0-1.el8.noarch
ovirt-hosted-engine-ha-2.4.9-1.el8ev.noarch

Then the deployment has failed just like it did over RHEL8.6:

~]# hosted-engine --deploy
[ INFO  ] Stage: Initializing
[ INFO  ] Stage: Environment setup
          During customization use CTRL-D to abort.
          Continuing will configure this host for serving as hypervisor and will create a local VM with a running engine.
          The locally running engine will be used to configure a new storage domain and create a VM there.
          At the end the disk of the local VM will be moved to the shared storage.
          Are you sure you want to continue? (Yes, No)[Yes]: 
          It has been detected that this program is executed through an SSH connection without using tmux.
          Continuing with the installation may lead to broken installation if the network connection fails.
          It is highly recommended to abort the installation and run it inside a tmux session using command "tmux".
          Do you want to continue anyway? (Yes, No)[No]: yes
