In this commit we add run_master_in_recovery_mode(), which groups all necessary initialization steps, which master should perform to be able to enter in its polling loop (run_master()), when it fails while parsing its new config. As exit_on_failure() is now adapted for master recovery mode. Let's register it as atexit handler, when master enters in this mode. And let's remove atexit_flag variable for master, because we no longer use it. We also slightly refactor here read_cfg_in_discovery_mode() in order to call run_master_in_recovery_mode() for the case, described above. Warning messages are mandatory before calling the run_master_in_recovery_mode() as this allows to stop haproxy with error, if it was launched in zero-warning mode. So, in recovery mode master does not launch any worker. It just performs its necessary initialization routines and enters in its polling loop to continue to monitor the existed worker process.
HAProxy
