MiddlewareWithConfig method in comment but not exists

[roger-codina]

Hi guys,

If I am not mistaken, I think that this comment refers to an old method or a not implemented one:

go-agent/v3/integrations/nrecho-v4/nrecho.go

Line 73 in c611087

// e.Use(nrecho.MiddlewareWithConfig(nrecho.Config{App: app}))

The only way to create the middleware handler is calling the Middleware function using a *newrelic.Application as the first argument and passing as variadic arguments ConfigOption types.

So, I think that the comment should be fixed to document the current behaviour of the function or implement that method :)

Cheers!
