Assorted e2e test updates

[r-c-n]

• Fix pipeline test (sync it to Node model changes)
• The "test" service of test-docker-compose.yaml no longer launches the tests on startup. Update the run_e2e_tests.sh script to start the service and run the tests.
• Fix inconsistencies in pytest dependencies

One solution is to mount tests/e2e_tests directly in test-docker-compose.yaml.

- './tests/e2e_tests:/home/kernelci/e2e_tests'

Another solution is to update all the dependecy markers to use test/e2e_tests/* instead of e2e_tests/*

@pytest.mark.dependency(
    depends=['tests/e2e_tests/test_user_creation.py::test_create_regular_user'],
    scope='session')

I think the first one looks easier than updating all the tests.

The first solution didn't work, but I don't understand why. pytest only raises these warnings for some dependency headers but not for others, totally inconsistent. I ended up fixing all the dependency paths, that's the only thing that worked.

I also added a fix for the pipeline test (model-related) that I didn't catch earlier because that test was being skipped.

Tested OK.
