Issue:
RFE: Mark tests that require internet?
Would you be willing to consider a mark or option to exclude tests that require internet access (ie, PyPI)?

Use case would be: running tests in package build systems that prohibit internet access.

Pull request description:
tests: add network marker
Fixes #648. Adds a network marker for tests using the network.

Tested by disabling wifi and running `pytest -m "not network"`.
