Support TLS 1.3 ticket based session resumption

See new API added in Node.js 11.10.0, [session event for TLS socket](https://nodejs.org/api/tls.html#tls_event_session). We use `getSession` to reuse the session negotiated by the control connection for all subsequent data connections. Apparently, this is not good enough anymore for TLS 1.3.
