tests: Exclude docker tests from regular pytest runs

- Add tests/docker to norecursedirs in pyproject.toml to prevent
  docker tests from running during regular test suite (they require
  docker and the requests library)
- Add -p no:cov to docker integration workflow to disable coverage
  plugin since pytest-cov is not installed in that environment
