[tests] Add a pre-setup setup method and smoke tests

First, add a "pre-setup setup" method, in the form of `pre_sos_setup()`,
that can be used in the way the traditional `setUp()` method would be
used (but can't because that's our entry point for executing our sos
runs). This method will be executed _prior_ to any mocking.

Second, add a smoke test that enables all plugins that exist in the
local branch being tested. This will test that doing so does not
generate any exceptions and that some expected warnings from select
plugins are displayed.
