Traceback when attempting to run functional test directly

[Dave McCowan]

It is nice to have the choice to run functional tests both through tox and manually.

This used to work, but now throws an attribute error if certain environment variables are not set.

ERROR: functionaltests.api.v1.functional.test_quotas.QuotasTestCase.test_get_quotas_with_defaults
----------------------------------------------------------------------

    Handle case of no logging environment variables

    When running functional tests manually, the expected environment variables
    typically set by tox may not be set. This patch avoids an exception and
    lets the test run with the defaults.
