Reduce tests which require the network

[atugushev]

What's the problem this feature will solve?

Currently, we have 13 tests that require the internet. We could reduce this number to 3. All tests marked as @pytest.mark.network could be refactored to use local package small-fake-with-deps, except probably those tests, which related to URL/VCS packages:

• test_editable_package_vcs
• test_generate_hashes_with_url

or do realistic (functional) tests, which is test_realistic_complex_sub_dependencies.

Describe the solution you'd like

1. Replace six and setuptools requirements with small-fake-a and small-fake-b in tests/test_data/packages/small_fake_with_deps/setup.py
2. Refactor the following tests to use small-fake-with-deps package:

• test_editable_package
• test_locally_available_editable_package_is_not_archived_in_cache_dir
• test_generate_hashes_with_editable
• test_generate_hashes_verbose
• test_allow_unsafe_option
• test_get_hashes_local_repository_cache_miss
• test_generate_hashes_all_platforms
• test_generate_hashes_without_interfering_with_each_other
• test_editable_top_level_deps_preserved

3. Move parameters related to small-fake-with-deps from test_url_package to a separate test test_local_url_package and replace six to small-fake-a.
4. Remove small-fake-with-deps-a package and its wheels, and refactor test_annotate_option to use small-fake-with-deps.
