Debugging adapters

When some error occurs - it can be seen in server console.

But it would be convenient also to forward to client. At the moment just empty response is returned.

It can be also useful to provide exact error message, but perhaps not for all clients, but for administrators only (so admin token should be required).

And it would be also good to have additional info in response, such as channel/provider name. That is important for successful responses too.

Thank you for your response for debugging and other issues! I've been excercising for my driver license these days, and I'll check these issues in next few weeks.
