Allow binding to unix domain socket

[julianlam]

Currently NodeBB binds to port numbers (e.g. 4567), but it would be beneficial, especially on servers with high load, if binding via a unix domain socket was possible.

I'd just override port, since it behaves similarly...

Ironically, I didn't have to actually change anything, NodeBB ran perfectly fine on unix domain sockets 😄

Needed to fix umask for the process though.

@julianlam Hi Julian, I would like to bind nodebb to a unix socket as well for performance reasons. Can you share how you did this?

Thanks.
