Description of problem:
Add a warning to explicitly use either IPv4 or IPv6 during deloyment.
The default for 4.3 and bellow was IPv4, from 4.5 and above we have this one changed to use IPv6 as default method during the deployment on dualstack environments. Please add warning for the users in initial state of the deployment, to use either --4 or --6 instead of not using anything and simply running hosted-engine --deploy, as this may severely impact on 4.3->4.5 or 4.5 restore or simple 4.5 clean deployments. 
If possible and customer made a choice, either hosted-engine --deploy --4 or hosted-engine --deploy --6, then the warning should not be shown during the deployment, just like it happens for tmux.

This request comes from https://bugzilla.redhat.com/show_bug.cgi?id=2087735 issue, caused by this flow.
