Add META test to legacy protocol and Report connection info or NDT7 clients
This change includes three new features:
- Full support for PLAIN,JSON and PLAIN,TLV clients
- Full support for the META test in the legacy protocol
- Additional monitoring of client test suites
- Provide NDT7 clients with the connection four tuple and the UUID
The legacy protocols should provide complete legacy client support. We will be monitoring to the client test suites to determine whether this version adequately support all legacy clients.
