Following a discussion we had during the summit, here is one series to
fix a race between an application thread and the telemetry thread
handling requests on ethdev ports.

The problem may be generic to other device classes providing telemetry
callbacks, but for now, this series goes with a simple and naive
approach of putting locks in the ethdev layer.

v2: added new telemetry api to register callbacks with a private arg.

  telemetry: add api to register command with private argument
  ethdev: fix potential race in telemetry endpoints
