systemd: add support for reloading daemon configuration through systemd
This adds support for reloading the docker daemon
(SIGHIUP) so that changes in '/etc/docker/daemon.json'
can be loaded at runtime by reloading the service
through systemd ('systemctl reload docker')
Before this change, systemd would output an error
that "reloading" is not supported for the docker
service;
systemctl reload docker
Failed to reload docker.service: Job type reload is not applicable for unit docker.service.
After this change, the docker daemon can be reloaded
through 'systemctl reload docker', which reloads
the configuration;
journalctl -f -u docker.service
