v2.17.3

Enhancements

• [Stager] Rescue and report staging errors with telemetry

  Staging errors from queue contention or other database issues would cause the top level stager process to crash. Eventually that could shut down the entire Oban supervision tree. Now we rescue standard database connectivity issues instead and report them as errors in telemetry.

• [Telemetry] Include result in job exception telemetry

  Returning an {:error, reason} tuple triggers an :exception telemetry event, but there's still a return value. Exception events for crashes, raises, timeouts, and kills will have a nil result value.

• [Queue] Add producer handle_call clause for engine put_meta calls.

  Previously, the only way to put meta was through a non-blocking notification to handle_info.
