Epic Goal

• Allow the user to select a host to be Node 0 interactively after the booting the ISO. On each host the user would be presented with a choice between two options:

1. Select this host as the rendezvous host (it will become part of the control plane)
2. The IP address of the rendezvous host is: [Enter IP]

(If the former option is selected, the IP address should be displayed so that it can be entered in the other hosts.)

Why is this important?

• Currently, when using DHCP the user must determine which IP address is assigned to at least one of the hosts prior to generating the ISO. (OpenShift requires infinite DHCP leases anyway, so no extra configuration is required but it does mean trying to manually match data with an external system.) AGENT-385 would extend a similar problem to static IPs that the user is planning to configure interactively, since in that case we won't have the network config to infer them from. We should permit the user to delay collecting this information until after the hosts are booted and we can discover it for them.

Scenarios

1. In a DHCP network, the user creates the agent ISO without knowing which IP addresses are assigned to the hosts, then selects one to act as the rendezvous host after booting.
