deferred_connection

promise is not working because it is reset to null in the connectFailure callback.
removing the set_value() from the connectFailure callback fixed the issue of subscription after promise.

Test:<br>
start mosquitto broker and the publisher test on a remote desktop.<br>
disable the internet connection on the subscribing desktop.<br>
start the subscriber test on the subscribing desktop.<br><br>
<i> at this point, the mqtt client keeps returning to the connectFailure callback </i><br><br>
enable the internet connection again.<br><br>
<i> at this point, the mqtt client returns to the connectSuccess callback. subscriptions are activated and data is coming in.</i>

…k. removing the set_value() fixed the issue ofsubscription after promise.

added LWT ( last will & testament ) option to mqtt connect.

added support for a last will & testament message. LWT settings are not required for connection, but can be provided as optional parameter when calling the mqttclient connect function. ( see publisher test case ). The parameters to be added are the topic to publish on and the message to be published in case of a connection disruption.
