> when invocation timeout or isolated or other scenes, it's very difficult to find the problem, we must improve related ability
>  
> we can create projects in "integration test" to build business like: 3rd -> edge -> A -> B, and enhance fault injection to support inject error or timeout on:
>  * consumer handler request
>  * http client filter beforeSendRequest
>  * http server filter afterReceiveRequest
>  * producer handler request
>  * producer business method
>  * producer handler response
>  * http server filter beforeSendResponse
>  * http client filter afterReceiveResponse
>  * consumer handler response
> that means there are 21 places will inject faults at least.
> when fault happened in any place, we should be able to find problem from log.
>  
> this is a big and very important task, feel free to create subtasks, eg: 
>  * provide a marker instance by invocation, to log invocation id and traceId by %marker
>  * enhance fault injection
>  * provide a way to view internal status
>  ** discovery tree status
>  ** isolation status
>  ** eventbus subscribers
>  ** ......
>  * when timeout happened, how to find problem
>  * when error happened, how to find problem
>  * when isolation happened, how to find problem
>  * ......
