More metadata from client trace logs to the server

It may help production support if the server logged more metadata about the connected clients. For example, are the client trace logs enabled, what bindings are they using etc.

Start by tracing how client trace-log settings and bindings are represented and communicated to the server; the issue does not name files, tests, or entry points. Done means the server logs the requested connected-client metadata in a defined, support-useful format, with appropriate tests or validation.
