Proposed Changes

This PR addresses #11171

The proposed changes catch the exit signal emitted by ranch:handshake in rabbit_networking:handshake and log an error message in case the reason for shutting down the connection is other than closed.

The reason for not logging closed shutdown exit exceptions has been added as a context comment in the source.
