Update docker-compose services

[BboyKeen]

Hey there,

You'll find in this PR a few updates

• Schema update scripts are inline with the use of the standard postgres user.
• $USER variables are not used anymore in schema update scripts
• Previously built images for Postgres/Postgis and Redis are not used anymore in docker-compose
• We use the dedicated volumes feature for Postgres data now
• The obsolete links directive was removed from the docker-compose

All tests are green in local with these updates

Hello, thanks for the PR (and the other ones)

I didn't see a notification, thus only seeing this now.

I'm wondering about the postgre image change: this image contains anonymized data from an old extract of c2c db, it's not used in the tests?

[BboyKeen]

Interesting. I may have missed something for this part. However all tests are green without it so I think it's only used as dev fixtures.

I can revert this part if necessary but this image is quite old and it's not easily updatable..

Maybe we should prefer having a dumped anonymized SQL file to load at dev database init.

Hello, again sorry for having been very absent recently

I think we can merge this anyway, all tests pass, and I don't really see why we would need existing data for tests that don't use it
