Run s3 primary tests sequential

[kesselb]

• Resolves: /

Summary

The test matrix (https://github.com/nextcloud/server/blob/master/.github/workflows/s3-primary.yml) defines two jobs. Both require and define a minio service to run the tests.

Because the jobs run within the same docker network and the same github runner, only one minio instance can use port 9000.

First approach

Using a random port for minio to avoid conflicts.

Random ports are not a solution because there is a chance that the same random port is assigned. Sounds unlikely but happend here for multiple test runs.

Before	After

Second approach

Use jobs.<job_id>.container works, but makes it impossible to fetch the dockers logs for the minio container.

Third approach

Set max-parallel to 1 to execute the jobs sequential.

ERROR Unable to initialize console server: Specified port is already in use

Last CI run failed with the same error message like before 😨

I wonder how binding the console port could fail when the console is not even exposed to the network.
docker ps show two different containers for the CI jobs.

Pushed another change to generate a random port console (9001) too.
However, I'm not too certain about it anymore.
