Add possibility to hide some parts of requests/response

[liveforeverx]

Should be done on security reasons.

It should be possible to remove some parts of requests in logs, based on configuration (for example).

Should we have two different options to remove parts of request and response or one option for request and response?

That should be one option IMHO. If you don't want to see the data in the request, you most likely also don't want to see it in the response.

like hsychla said: if we decide to hide the information, we don't want it to be in any message. So one option is sufficient.
