With refactored master-worker architecture master and worker processes parse its parts of the configuration. Worker could have a huge configuration, so it will take some time to load. As now HAPROXY_LOAD_SUCCESS is set to 1 only after receiving the status READY from the new worker cli_io_handler_show_loadstatus() may exit very fast by showing load status 0, and in such case and mcli socket will be closed. This already breaks some regression tests and can confuse some APIs. So, let's slow down the load status delivery. If in the process list there is still some process, which is loading (PROC_O_INIT). appctx task will sleep in this case for 50ms and then return 0. cli_io_handler_show_loadstatus() is called in loop, so with such pacing, there is a high chance that the next time, when we enter in its scope all processes will have the state READY. Like this master CLI connection socket won't be closed until the loading of the new worker is really finished, thus the reload status and logs (Success=1/0) will be shown in synchronious way.
