> {{kafka-storage.sh format}} accepts a {{cluster-id}} argument. While the recommendation is that users can generate a random uuid using {{kafka-storage.sh random-uuid}} command, the users are free to generate a cluster id out of band.
> The {{format}} command should therefore perform validation on the cluster-id passed as we risk using one which is invalid. Gotchas can include:
> * Not using URLEncoding when using base64
> * Using base64 encoding with padding
> * Being unlucky and using a reserved UUID
