Docker image: docker pull ghcr.io/akvorado/akvorado:2.0.0-beta.2
Full changelog: v2.0.0-beta.1...v2.0.0-beta.2

This release introduce a new component: the outlet. Previously, ClickHouse was
fetching data directly from Kafka. However, this required to push the protobuf
schema using an out-of-band method. This makes cloud deployments more complex.
The inlet now pushes incoming raw flows to Kafka without decoding them. The
outlet takes them, decode them, enriches them, and push them to ClickHouse. This
also reduces the likeliness to lose packets. This change should be transparent
on most setups but you are encouraged to review the new proposed configuration
in the quickstart tarball and update your own configuration.

As it seems a good time as any, Zookeeper is removed from the docker compose
setup. ClickHouse Keeper is used instead when setting up a cluster. Kafka is now
using the KRaft mode. While migration is possible, it is easier to start from
scratch:

# docker compose down --remove-orphans
# docker compose rm -v kafka
# docker compose pull
# docker compose up -d

• 💥 outlet: new service

• 💥 docker: switch Kafka to KRaft mode
• 🩹 console: fix deletion of saved filters
• 🩹 console: fix intermittent failure when requesting previous period
• 🩹 docker: move healthcheck for IPinfo updater into Dockerfile to avoid
  "unhealthy" state on non-updated installation
• 🌱 docker: enable access log for Traefik
• 🌱 docker: update ClickHouse to 25.3 (not mandatory)
• 🌱 docker: update Traefik to 3.4 (not mandatory)
• 🌱 docker: switch to Prometheus Java Agent exporter for Kafka
• 🌱 orchestrator: move ClickHouse database settings from clickhouse to clickhousedb
• 🌱 inlet: improve performance of classifiers
