Equivalent to '/etc/init.d/networking restart' in a netplan world

[James Troup]

With complex network setups or when networking is in a wonky state and you're not sure how/why, '/etc/init.d/networking restart' was a nice 'reset the world to a known good state' tool in an ifupdown world. It'd be very useful for me if netplan had something similar as my only other option appears to be 'reboot', which is a very big hammer.

Netplan doesn't try to be the exclusive tool for networking. So it cannot just wipe out any applied networking configuration, that might originate from another tool (e.g. Open vSwitch).

The `netplan apply` command should reset/re-apply the interfaces as defined in /etc/netplan/*.yaml configuration. But not touch anything else.
