Building on issue OSPRH-3667 which extracts crc into a nodepool node, this epic tracks extracting the EDPM nested VMs into nodepool nodes.

The current approach requires a large host VM, with nested VMs inside it representing each bare metal node. This has the following disadvantages:

• Nested virt can be significantly slower for the workloads running within them
• Nested virt can be less reliable, raising the failure rate of CI jobs with no clear root cause
• It is not possible to enable FIPS in test workloads in some environments, due to lack of available entropy

This Epic is to track implementing Redfish virtual media boot with sushy-tools using VMs from the test environment (such as Zuul nodepool nodes)

The impact of this work will be:

• Increased reliability of upstream jobs
• More but smaller VMs required for bare metal jobs
• The ability to reliably test FIPS upstream
• All of the above, but for downstream jobs too.
