Maybe it's more generic than ToLogrusFields

Maybe it's more generic than ToLogrusFields

And ToLogrusFields is used in LinK (https://github.com/Scalingo/link/blob/master/models/ip.go#L20) :D

Do we want something more generic? I mean, this function returns a logrus.Fields anyway. So it's really specific to this dependency, isn't it?

[john-scalingo]

I did not know that LogFields existed. IMHO it's better than ToLogrusFields WDYT ?

I find both ok. If both of you find LogFields better, then I'll rename :)
