This PR introduces various changes to improve the CI pipeline. Most importantly, it introduces mock response so no remote server is called by the CI. The previous remote request made the CI unstable due to rate limits (runner IP being blocked by remote servers).

Overview of changes:

• Mock response for remote requests (to a avoid time outs etc.)
• Slow test cases are skip with pytest mark
• Multi-testcases are refactored as single text methods (easier to spot failing test cases and to auto-load the mock responses)
• Fixed wrong "False" in slow_ci() function.
• DNS error handling for windows + macos
• Additional unit tests for better test coverage

By default, all remote requests are mocked. To change this behaviour and actually call remote APIs (if you run this from a whitelisted IP address), the following environment variable can be set:

export DISABLE_MOCK_RESPONSES=1

If the remote APIs change, new mock data can be semi-automatically collected by setting another environment variable, running corresponding unit tests, and overwriting existing mock data in tests/data/mock_responses:

# set environment variable (DISABLE_MOCK_RESPONSES should not be set)
export SAVE_MOCK_RESPONSES=./tmp/mock_responses
    
# run the test for what mock data should be saved to $SAVE_MOCK_RESPONSES/<test_file>/<test_func>.jsonl
pytest tests/test_cli.py::test_basics

I need an IP to look in some logs. Both of these failed because the "block_proxies" script hates this particular Github CI IP.
