The UI will crash and show a stack trace when view the VM nics details, if we add a new interface to the running VM.

1. Create a VM
2. login into VM via console
3. Add new interface with commands below
4. Go to the VM network tab
5. crash (can take a bit time, until the agent update the status)

sudo ip link add br0 type bridge
sudo ip link set br0 up
sudo ip addr add 10.11.12.13/14 dev br0

When accessing the UI to inspect the VM network, the UI will crash

1. The VM view should not crash
2. (optionally) show the new interfaces as read-only ephemeral interfaces.

The VMI yaml status will include the new interface detail, which don't have any refs in the VM CR yaml.
