Logging of message payloads

[clstb]

Hello,

I can't seem to find a way to log received and published message payloads without wrapping the default message handlers. Could we make the corresponding log lines configurable inside client.go? Would also be happy to implement this if we agree it's something useful.

As you say wrapping the library is probably the simplest option for this (for received messages you can also use your own router). Personally I see this as a fairly specific requirement, that can be accommodated fairly easily (via wrapping, which I believe is a reasonable solution), so am not sure that there is much benefit to adding this into the library (every option added to the library increases complexity).

Having said that, if you feel that adding it to the library would provide significant benefits then feel free to propose something.
