When configuring TLS between the console proxy (where the n-novnc
service runs) and the compute host, some configuration for QEMU needs
to be done on the compute host. The existing code for this requires the
n-novnc service to be running, which it is in a single node all-in-one
deployment. However, when running in a multinode deployment, the
n-novnc service runs only on the controller and not on the subnode.
Yet, we need to configure QEMU on the subnode compute host as well.
This removes the n-novnc service requirement to enable TLS QEMU
configuration to occur on a compute subnode in a multinode deployment.
