RHV AIO Install for Lab

This, loosely, documents installing RHV as an all-in-one server. This is not supported and has some flakiness, particularly for updates. Additionally, because it's a lab, no "real" storage was used.

The Server

The physical server used for this has 8 core, 32GB RAM, and a 512GB NVMe drive connected to the network using a single 1 GbE link. You'll need at least 200GiB of storage to comfortably host more than a couple of VMs.
