This PR adds support for using pre-shared keys in TLS connections. MQTT servers seem to start to support this, at least mosquitto does. This is an alternative to generating a self-signed cert and then distributing the cert to all mobile devices. With PSK one can now generate a long random hex string and simply use that as key. It also makes it easy to have multiple identity->key pairs, basically they act like passwords.
I would be happy to write some docs for this, but am not sure where to add given that WiFiClientSecure doesn't have any docs.
