Implemented ReloadConfig method in server
A new ReloadConfig function has been added to the Server in server.go which reloads server configurations and updates the Server's conf field as well as the configured Ruleset. Changes have also been made to the handling of the SIGHUP signal in main.go, using this new function to reload configurations and updating the logs accordingly.
