functional tests should be grouped with other tests (unit and
integration tests). as part of this commit the "common" module
was renamed to just "base", this was done for simplicity.

the post_test_hook.sh file was also copied to the functional module
since it should live there. a separate change to the infra repo
will be made to call the new location, once that is merged we
can remove the old one (a new change will also be posted for that)

Use the format options for functional tests so we can have more
assertEquals and less assertIn.

Remove unique class names because they are module scoped.  Also,
add cleanup of the tmp file in the object test.

Have the functional tests running with less customization and
less shell.  This change will allow the functional tests to be
run against any cloud set up in the environment.

The tests should be further divded by project version, similar to
the structure of the unit tests.
