Merge remote-tracking branch 'origin' into richard-config-loading-test
Removed the target repose node (the one with no filters or destinations) and replaced it with an HTTPServer-based class on a separate thread.
Removed the simple-node config set.
Split config files into good/bad/common, so that we're only changing a single config file during each test.
Added an override of log_message, so that we can use proper logging rather than printing to STDERR as the base class does.
