Sets the socket timeout used by the client. This determines how long the client will wait for incoming data when it expects data to arrive - for example, whilst it is in the middle of reading an MQTT packet.

By default, it is set to 15 seconds - as defined by the MQTT_SOCKET_TIMEOUT constant in PubSubClient.h.
