vm based providers: Change default dns host port (#903)

Since some OS (i.e RHEL), already listens to 127.0.0.1 on port 53, change the default host port to the dedicated gocli dns port (31111). It can be overridden by setting KUBEVIRT_DNS_HOST_PORT. Signed-off-by: Or Shoval <[email protected]> Signed-off-by: Or Shoval <[email protected]>
