Refacter API server emphasis on logging

* To aid in debugging log API request and response bodies at trace
  level. Events can be correlated using the X-Reference-Id.
* Server now echos X-Reference-Id from client if set, otherwise
  generates an unique id.
* Move logic for X-Reference-Id into middleware
* Change uses of Header.Add() to Set() when setting Content-Type
* Log API operations in Apache format using gorilla middleware
* Port server code to use BaseContext and ConnContext

Fixes #10053
