Custom fields in log statement?

[maros7]

Hi, I'm wondering if you'd consider a PR for adding functionality to make it possible to add custom fields to the log statement? E.g. by having something like:

func WithCustomFields(logger *zap.Logger,
	timeFormat string,
	utc bool,
	customFields ...func(c *gin.Context) zap.Field,
) gin.HandlerFunc {

...

Our use-case is that we need to log the return headers.
