External services are not available when we execute in Helm.
- Added a way to mark REST API tests that require external services to
run
- Changed the way of filtering tests in Helm tests
Currently, we can't execute external service mocks in tests, and we
ignore related tests in the Helm
execution command. But this command may be outdated, because Helm tests
are not executed in each PR.
This PR allows to indicate related tests and filter them out without the
need to synchronize the CI command.
`pathlib` improves code readability and type safety. It is already used
in some of the tests; convert all remaining `os.path` usage to `pathlib`
equivalents.
