Make timeout on exit configurable

 - make timeout in at_exit handler configurable (was hardcoded to 10s), new api:
   int dlt_set_resend_timeout_atexit(uint32_t timeout_in_milliseconds);
 - add option -t to dlt-adaptor-stdin to set timeout in at_exit_handler
 - add option -t to dlt-example-user to set timeout in at_exit_handler
