    Do not check requirements when loading entry points

    Update the calls to pkg_resources to avoid forcing a requirements check
    when the plugins are being loaded.

    There are 2 versions of the entry point API in different releases of
    setuptools. In one version, the require keyword argument can be passed
    to load(). In the other, separate methods resolve() and require() need
    to be used. This change updates the mock and fake objects to support
    either, since the fakes are subclasses of the EntryPoint class in
    pkg_resources.

    It would be better to replace the calls to pkg_resources with stevedore,
    which provides a more stable API, abstracts away this difference, and
    provides an API for creating test managers directly. That change would
    have required more extensive updates to the test suite, though, and
    since I'm not as familiar with this code base as others will be, I will
    leave those changes for someone else.
