## Description Implements libp2p#4010, which was closed. It was closed because it appeared that the Identify specification doesn't dictate this feature. But, in the discussion on the specs repo (libp2p/specs#597) it is mentioned that this might very well be an implementation detail. This PR introduces a `hide_listen_addrs` flag that will prevent our listen addresses to be included, effectively only sharing our external addresses. <!-- Please write a summary of your changes and why you made them.

Fixes https://github.com/libp2p/rust-libp2p/issues/XYZ. --> ## Notes & open questions An alternative implementation would be to allow us to filter the addresses we are sending out, by providing a closure I imagine. <!-- Any notes, remarks or open questions you have to make about the PR which don't need to go into the final commit message. --> ## Change checklist <!-- Please add a Changelog entry in the appropriate crates and bump the crate versions if needed.
