Fixes

General fixes

• Issues: #4522. A data race happened when emptying buffers of a failing broker, in its thread, with the statistics callback in main thread gathering the buffer counts. Solved by resetting the atomic counters instead of initializing them. Happening since 1.x (#4718).
• Issues: #4948 Features BROKER_BALANCED_CONSUMER and SASL_GSSAPI don't depend on JoinGroup v0 anymore, missing in AK 4.0 and CP 8.0. This PR partially fixes the linked issue, a complete fix for all features will follow. Rest of fixes are necessary only for a subsequent Apache Kafka major version (e.g. AK 5.x). Happening since 1.x (#5131).

Telemetry fixes

• Issues: #5109 Fix for poll ratio calculation in case the queues are forwarded. Poll ratio is now calculated per-queue instead of per-instance and it allows to avoid calculation problems linked to using the same field. Happens since 2.6.0 (#5017).
