FR: Support arbitrary syslog facilities

[jaredledvina]

Due to the log volume from gopassivedns, we'd like to configure it to log to a specific syslog facility to further separate it out from the rest of the system logs. However it seems that,

gopassivedns/log.go

Lines 244 to 283 in aa047e1

	case "KERN":
	return syslog.LOG_KERN, nil
	case "USER":
	return syslog.LOG_USER, nil

	return syslog.LOG_MAIL, nil

I'm not sure what you're looking for here. Syslog facilities are defined in https://tools.ietf.org/html/rfc3164, as far as I know you can't add arbitrary new ones. Mostly people handle this by using one of the local* facilities. Could you tell me a little more about what you would like this to look like?

Ah whoops, I meant to superceed this with #25 but apparently missed actually doing that. Sorry!
