Use fixtures from keystoneclient for static data

We should use the fixture generation code from keystoneclient rather
than keep our own copies of the token and discovery structure.

cleanup files that are created for swift functional tests

Currently this portion of code is also being run when running
tox to debug local tests. Which is very annoying since a developer
will end up with a bunch of uuid files. Rather than creating it
once per run, we can have a setup/teardown that is handled safely.

Create functional tests for the example code

Very simple functional tests that kick off the example python
code that was created. This will ensure that the examples do
not bit rot.

Run with --debug enabled to aid debugging.
