Implement nbd-proxy as a part of bmcweb

Nbd-proxy is responsible for exposing websocket endpoint in bmcweb.
It matches WS endpoints with unix socket paths using configuration
exposed on D-Bus by Virtual-Media.

Virtual-Media is then notified about unix socket availability through
mount/unmount D-Bus methods.

Currently, this feature is disabled by default.

Tested: Integrated with initial version of Virtual-Media.
