Config in stress tests is broken

[Matthew Treinish]

The stress test suite doesn't work currently because tempest.config migrated to using cfg from oslo, but the config module in the stress test suite was never updated for these changes.

    Update stress tests to properly use tempest.config

    When tempest.config was switched over to using oslo the stress tests
    weren't updated with those changes. Also subsequent changes to the
    tempest options were not updated in the stress test suite. This left
    the stress tests unusable because it couldn't get the needed
    information from config. This commit updates the stress test suite
    to properly use tempest.config. It also adds a new section to the
    config file for stress test specific options.

    Fixes bug 1133012
