[PATCH v2 0/2] log negotiated protocol version.

This series adds logging of the negotiated wire protocol via trace2 on both client and server.

Changes in V2:
* adds a format_protocol_version() helper function
* adds tests
* bug fix: actually log on the server side, rather than twice on the
  client
* moves the trace statement closer to the actual version negotiation
  code

Josh Steadmon (2):
  protocol: add protocol version formatting function
  connect, protocol: log negotiated protocol version
