Client disconnection without warnings

[djbaldey]

If there is a "connect" method, then why is there no "disconnect" method?

When we shut down the application, warnings of an increased level of attention appear in the Asterisk log:

 Deactivating Stasis app 'queue'

The disconnect method is necessary to close the socket connection properly, and not to hard break it.
