Upgrade kafka nodes to bullseye

Upgrade the kafa nodes:

• journal0.internal.staging.swh.network (staging's kafka was migrated to storage1, which can't be upgraded to bullseye as swh-storage and swh-objstorage are deployed on it)
• kafka[1-4].internal.softwareheritage.org

Upgrade plan:

• disable puppet
• upgrade buster packages
• stop and disable kafka
• stop and disable zookeeper
• reboot if needed
• upgrade to bullseye following the plan described in #3749 (closed)
• Try to reboot, if the network is not working
  • edit the /etc/network/interfaces file and comment the physical interface declarations

auto enp94s0f0np0
iface enp94s0f0np0 inet manual
  mtu 9000
# interface enp94s0f1np1 configuration
auto enp94s0f1np1
iface enp94s0f1np1 inet manual
  mtu 9000

• Remove the interface configuration on puppet (kafka[1-4].internal.softwareheritage.org` files) before restarting puppet

• restart and check zookeeper status

• restart and check kafka status (wait for the cluster to recover[1])

• re-enable puppet
