To enhance operatability for the service using norman framework, It's better to expose internal state as detail as possible. This is the just starting point but at least which handler is executed often and which handler with which key's execution is often failed metrics is very useful to spot the place operator have to dig in when something happened. So this commit added 2 metrics. 1: handler execution total count 2: handler execution failure total count
