K8SPSMDB-1192: Introduce e2e-test pytest wrapper

[jvpasinatto]

CHANGE DESCRIPTION

This PR adds a wrapper script for running e2e tests with Pytest.
Logs from the tests are captured and only shown on failures alongside the state of K8s nodes at the time.
Test reports are generated and stored by default in the e2e-tests/reports directory.

This PR also adds a github action to run mypy and ruff on the python code.

How to run using uv:

Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

Create venv and install/sync dependencies
uv sync

Run all tests
uv run pytest e2e-tests/test_pytest_wrapper.py -v -s

Run specific test
uv run pytest e2e-tests/test_pytest_wrapper.py -v -s --test-regex '^one-pod$'

Run a test suite
uv run pytest e2e-tests/test_pytest_wrapper.py -v -s --test-suite backups

Run and collect k8s resources
uv run pytest e2e-tests/test_pytest_wrapper.py -v -s --test-regex '^one-pod$' --collect-k8s-resources

[gkech]

I think we need to add to gitignore e2e-tests/__pycache__/

[gkech]

we can maybe add the reports/ directory as well to avoid unintentional report file commits.
