* 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 Signed-off-by: Jhon Honce <jhonce@redhat.com>
