vm_websocket: Add websocket handler

On receiving a websocket request on endpoint /vm/0/0,
connect to the nbd-proxy app and send/receive stdio.

Tested: Verified that the host could see the virtual
media usb device, mounted it manually and checked
the contents of the iso file used for the test were
there. To test, used the html and js script:
https://github.com/openbmc/jsnbd/tree/master/web
and an Ubuntu iso image file.
Verified that it worked after closing the websocket
(using the stop function from the html file), to
check that the processes were cleaned up and freed
up for a subsequent request.
