Pip-tools: Add @pytest.mark.network to tests which require the internet

[atugushev]

What's the problem this feature will solve?

It would be good to split the parameterized, and revise the tests unnecessarily using online data, and mark any real unavoidable online tests with a pytest marker called 'internet' or 'online' so that I (and other packagers) could use the following.
