Summary

Add:

journal (through kafka/zookeeper instance)
swh-storage-listener
swh-journal-publisher
swh-journal-client (dedicated client for the occasion)

Scenario is:

sql triggers on newly inserted objects (swh db) events
listener picked up those events, published those on the journal on temporary topics
publisher who is subscribed to the listener's topics, picked up those events, reified those associated objects, published them to the journal on new public topics
client who is subscribed on the origin/origin-visit public topics picked those up and logged them

Depends on D859
Depends on D863

Test Plan

docker-compose up

Load a repository, we should see logs about swh-journal-client logging events received (origin, origin-visit).

docker-compose.yml
21	why?
dockerfiles/swh-storage-listener/entrypoint.sh
30	`2>&1` to redirect stderr to stdout.

docker-compose.yml
21	i don't know, i'm planning on checking if it's useful or not.
dockerfiles/swh-storage-listener/entrypoint.sh
30	lol Right you are! thanks

It's not completely ready, i have for example:

the client that does nothing for the moment.
The listener and publisher are working but not completely.
The publisher somehow seems to not do anything in regards to origin/origin-visits
