Need to append "/index" to all requests on local setup

Describe the bug

On the local setup (docker-compose), one needs to append /index to all GET requests.

Expected behaviour

API as defined in the OpenAPI document.

Technical details

This is a workaround to a “fundamental design flaw” in MinIO, through which files can not have the same name as directories. This is not an issue on “proper” S3 compatible storages (e.g. AWS or OpenShift) and only affects local development - on open shift, the files are properly renamed. However, this is still a deviation from the documented API.

Possible Fix

Option A

• Remove MinIO and the “upload” distribution runner from the local setup, instead serve the files generated by the “assembly” runner from the local file system using something like nginx (config from mock server can be reused). This would enable easy end-2end scenario testing (submission to distribution), but would also mean that not all of our code is run locally.

Option B:

• Look for an alternative to MinIO that supports files and directories having the same name

Option C:

• Remove MinIO and force users to provide some S3 compatible bucket themselves (e.g. private AWS S3, etc.)

Option D:

• Add the “/index” suffixes to the actual API definition

Option E:

• Just leave this as is for now, wait for Apple/Google to finally release a backend API spec and then implement that instead. Any “fixing” of the current API probably needs to be thrown away in a few days anyways when they force an API spec onto us.

Option F:

• ???

The objectstore endpoint needs to be defined in the docker-compose.yml, see https://github.com/corona-warn-app/cwa-server/pull/228. This fixes the connection issue between was and cloudserver.

Thanks @CCFenner 👍 Saved my day… PR will follow in a bit, just some cleanup to be done.
