Release v22.127.0

Added

• Observable queries now report metrics for active subscriptions and pushed updates, and trace each push with a cratis.arc.query.push span. The metric and span names are available as constants on WellKnownTelemetryNames. (part of #2915)

Fixed

• An enumerable observable query over WebSocket now ends when the client disconnects while no item is ready, instead of keeping the connection handler waiting. (part of #2915)
