error tag is always is false in span, even return error in handler.
the code is here:
https://github.com/opentracing-contrib/echo/blob/master/middleware.go#L58~L63
if err := next(c); err != nil {
sp.SetTag("error", true)
c.Error(err)
}
sp.SetTag("error", false)
Maybe it should be changed to:
err = next(c)
if err != nil {
sp.SetTag("error", true)
c.Error(err)
} else {
sp.SetTag("error", false)
}
