Reorder middlewares and add test for must parse kafka version

[zhouzhuojie]

Reorder the middleware so that other stats logging can catch recovery middleware.

• Move recovery middleware closer to the application code
• Use logrus for recovery middleware logging, so that it can catch recovery error in sentry
• Add tests for mustParseKafkaVersion
