/**
* @brief Allows to create a new MQTT connection to a MQTT
* broker/server running MQTT over WebSocket.
*
* @param ctx The context where the operation will take place.
*
* @param client_identifier The client identifier that uniquely
* identifies this MQTT client from others. It can be NULL to let
* MQTT 3.1.1 servers to assign a default client identifier BUT
* clean_session must be set to axl_true. This is done automatically
* by the library (setting clean_session to axl_true when NULL is
* provided).
*
* @param clean_session Flag to clean client session or to reuse the
* existing one. If set to axl_false, you must provide a valid
* client_identifier (otherwise the function will fail).
*
* @param keep_alive Keep alive configuration in seconds after which
* the server/broker will close the connection if it doesn't detect
* any activity. Setting 0 will disable keep alive mechanism.
*
* @param conn A reference to an established noPollConn connection
* that is connecting to the MQTT over WebSocket server we want to
* connect to.
*
* @param opts Optional connection options. See \ref myqtt_conn_opts_new
*
* @param on_connected Async notification handler that will be called
* once the connection fails or it is completed. In the case this
* handler is configured the caller will not be blocked. In the case
* this parameter is NULL, the caller will be blocked until the
* connection completes or fails.
*
* @param user_data User defined pointer that will be passed to the on_connected handler (in case it is defined).
*
* @return A reference to the newli created connection or NULL if
* on_connected handler is provided. In both cases, the reference
* returned (or received at the on_connected handler) must be checked
* with \ref myqtt_conn_is_ok.
*
* <b>About pending messages / queued messages </b>
*
* After successful connection with clean_session set to axl_false and
* defined client identifier, the library will resend any queued or in
* flight QoS1/QoS2 messages (as well as QoS0 if they were
* stored). This is done in background without intefering the caller.
*
* If you need to get the number of queued messages that are going to
* be sent use \ref myqtt_storage_queued_messages_offline. In the case
* you need the number remaining during the process use \ref
* myqtt_storage_queued_messages.
*
* See \ref myqtt_conn_new for more information.
*
* <b>About reconnecting</b>
*
* If you enable automatic reconnect support after connection close
* (\ref myqtt_conn_opts_set_reconnect), remember to also configure
* the recover handler by using \ref myqtt_conn_opts_set_init_session_setup_ptr. That function should
* implement a complete reconnect and return a noPollConn reference
* used by the internal session setup. If you don't configure this,
* the function will disable reconnect support even if you enable it.
