Support req.socket.setAuthToken in MIDDLEWARE_HANDSHAKE_SC

[adnanalawiyat]

Handshake http request might already have necessary credentials to establish authentication, such as Authorization header. In this case, it might be desirable to call req.socket.setAuthToken within MIDDLEWARE_HANDSHAKE_SC even if

handshake event doesn't have authToken from client.

This submission ensures handshake socket response contains isAuthenticated=true for the above use case
