Helper methods for plugin and notification setup were previously defined on neutron.tests.base.BaseTestCase. The imports required to support these helpers were preventing the api tests from consuming tempest due to configuration conflicts that resulted between neutron and tempest. This change moves the helpers to a new module in tests/unit so that BaseTestCase can be safely used across all types of tests.
