feat: allow the interface on which the server will listen to be configured (#2015)

# What does this PR do?

It may not always be desirable to listen on all interfaces, which is the
default. As an example, by listening instead only on a loopback
interface, the server cannot be reached except from within the host it
is run on. This PR makes this configurable, through a CLI option, an env
var or an entry on the config file.

## Test Plan

I ran a server with and without the added CLI argument to verify that
the argument is used if provided, but the default is as it was before if
not.
