* fix PEP8 E721
do not compare types, for exact checks use `is` / `is not`, for instance checks use `isinstance()`
* remove redundant parentheses
* fix SiteWorker.run for empty job queue
local variable job is not assigned if queue was empty
when calling .run(), but it is used in exception handler.
* remove unreachable code in parse_diff_lines
* bug fix for unreachable code in is_worker_running
the code intended to check if *any* worker is running for
any site was *unreachable*.
this caused false negative results for site=None.
* check_failed_response: remove outdated part of docstring
* pull request template: fix relative path to LICENSE.txt
* fix typos
* use logger.warning, .warn is deprecated
Move existing tests into subfolder `tests/unit`. Write integration tests that actually run the installed borg executable. Those tests can be found in `tests/integration`. Those pytest fixtures that are the same for both kinds of tests remain in `tests/conftest.py`. The others can be found in `tests/integration/conftest.py` or `tests/unit/conftest.py`. This adds nox to the project and configures it to run the tests with different borg versions. This also updates the ci workflow to run the integration tests using nox.
* noxfile.py : Run pytest with a matrix of borg versions OR a specific borg version
* Makefile : Run using nox. Add phonies `test-unit` and `test-integration`.
* tests/conftest.py : Move some fixtures/functions to `tests/unit/conftest.py`.
* tests/test_*.py --> tests/unit/ : Move unittests and assets into subfolder
* tests/integration/ : Write integration tests.
* requirements.d/dev.txt: Add `nox` and `pkgconfig`. The latter is needed for installing new borg versions.
* .github/actions/setup/action.yml : Update to install pre-commit and nox when needed. The action now no longer installs Vorta.
* .github/actions/install-dependencies/action.yml : Install system deps of borg with this new composite action.
* .github/workflows/test.yml : Rename `test` ci to `test-unit` and update it for the new test setup.
Implement `test-integration` ci.
