Keep Alive timeout is represented by 2-byte unsigned integer, however the corresponding Kconfig option was limited to UINT8_MAX only. Also, similarly to regular MQTT, allow to disable the Keep Alive functionality by specifying the Keep Alive value to 0. Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
