[Story] Set max memory that containerized services can use

OpenChallenges

As a user, I want

As a developer, I want to control the max amount of memory that containerized services can use so that I can deploy all the required component of the OpenChallenges stack without slowing down or crashing my development instance.

Description

Look at the memory usage of dockerized services with docker stats and update the docker compose file of each project of the stack so that the maximum about of memory is specified. Each container should ideally have a bit of extra room.

Acceptance criteria

• Running docker stats after starting all the components shows that each container has a max amount of memory specified.
• The total amount of memory used by the stack should ideally be smaller than 8 GB if we want to developed on GitHub codespace. Otherwise we we just go with a bigger instance.

Done mainly in #1302.

The total amount of memory used by the stack should ideally be smaller than 8 GB if we want to developed on GitHub codespace.

The total amount of memory required is 9.5 GB when using relatively large error margins to ensure that the container do not crash frequently because of the lack of memory. The max memory could be optimized in the future.
