SIGTERM is used for graceful termination of services. This can allow a server to wait for all clients to close
connections while rejecting new incoming requests. To force instantaneous termination SIGINT signal must be sent.
On receiving SIGHUP configuration files are reloaded and a service is being reset and started again.Thus, SIGHUP
can be used for changing config options on the go. To achieve this each service should implement a *reset* method
which actually enforces changes to config options values.
On receiving SIGHUP configuration files are reloaded and a service is being reset and started again. Then all child
workers are gracefully stopped using SIGTERM and workers with new configuration are spawned. Thus, SIGHUP can be used
for changing config options on the go.
*NOTE:* SIGHUP is not supported on Windows.
