    [C++] Connect timer cancellation does not call timeout callback (#11486)
    
    Master issue: #11485
    
    When the PeriodicTask timer is cancelled it calls the handler
    which in turn ends up invoking the callback which closes
    the socket. This prevents the iteration over multiple endpoints
    until the connection succeeds. This change checks the error_code
    in the handler and returns if it is operation_cancelled,
    avoiding erroneously calling the callback.
