Call this function to establish, or re-establish, the Push Channel connection with the Good Dynamics proxy infrastructure Network Operation Center (NOC).
Establishing the connection involves a number of messages being exchanged with the NOC. The onStatus
callback in the delegate will be invoked as this progresses.
If mobile data coverage is lost after this function has been called, the Push Channel connection will stop operating. The Good Dynamics Runtime will automatically attempt to re-establish the Push Channel connection when coverage is regained. The Good Dynamics Runtime uses the native System Configuration feature to be notified of coverage status.
