Util function to transform string states

[martialblog]

Sometimes there's a need for this util function:

func convertStateToInt(state string) (int, error) {
	state = strings.ToUpper(state)
	switch state {
	case "OK", "0":
		return check.OK, nil
	case "WARNING", "1":
		return check.Warning, nil
	case "CRITICAL", "2":
		return check.Critical, nil
	case "UNKNOWN", "3":
		return check.Unknown, nil
	default:
		return check.Unknown, errors.New("invalid state")
	}
}

For example when providing a state via a CLI flag.

See:

• https://github.com/NETWAYS/check_prometheus/pull/66/files

Should we maybe provide this in the go-check lib?

@RincewindsHat What do you think?

Funny you should mention that. Thought the same thing :-)

So, yes. I think there is a place in the lib for that.
