docker: Cleanup docker-compose.yml file

Harmonize YAML formatting and remove some unused services:

• flower as it has always been deactivated

• kafka-manager as it is not mandatory to run the swh stack.

Migrated from D5089 (view on Phabricator)

Remove file commited by mistake

looks fine to me.

I'd maybe move the kafka-manager in another related journal related docker-compose file (if we have some).

I'd maybe move the kafka-manager in another related journal related docker-compose file (if we have some).

I tested it back yersteday, there is no automatic cluster detection and I did not manage to configure it manually so the removal. I guess we should find a more reliable tool if we need kafka monitoring in docker.
