After changing how we execute the storagenode-updater process we lost
timestamps in the log.
The fix is to start using zap logging.
The Windows Installer is changed to register the storagenode-updater
service in a way that the Windows Service Manager passes the
--log.output flag instead of the old --log.
The old --log flag is deprecated, but not removed. We will support it
for backward compatibility. This is required as the storagenode-updater
can auto-updated itself, but the Windows Service Manager of this old
installtion will continue passing the old --log flag when starting it.
