Proposed Changes:

We want to set up end-to-end tests and as a first step aim to re-enable the existing e2e workflow.

ToDo:

This PR is still in draft because we need to refactor the tests so that only end-to-end tests are triggered by the workflow. I updated the issue accordingly.

Notes for the reviewer

I tested the docker commands and pytest e2e/document_stores locally. The tests themselves took only 2 minutes. I also tested pip install .[inference,elasticsearch7,faiss,weaviate,opensearch,dev] locally. Just had to add quotes because of zsh locally. The GitHub action itself also runs through now too. Earlier there was an issue about opensearch still starting up when the first test was run.
