Release v2.8.4

Changelog

Go Version

• 1.17.10: Both release executables and Docker images are built with this Go release.

Fixed

• JetStream:
  • Consumer pending count was not correct when a stream had max messages per subject greater than 1 and a consumer that filtered out part of the stream was created (#3148)
  • Spurious 408 status messages sent to pull consumers. Also made some modifications to reduce lock contention between processing of acknowledgments and delivery of messages (#3149)
• MQTT:
  • Connections with same client ID but on different domains may have been detected as duplicates (#3150)
