Azure: Add netplan driver filter when using hv_netvsc driver (#539)
This fixes a long delay during boot of some instances. For Azure instance types using SR-IOV via the Hyper-V netvsc network driver, two network interfaces are created that share the same MAC, but only the virtual device should be configured and used. Updating the netplan configuration to filter on the hv_netvsc driver prevents netplan from trying to figure both devices.
