blueprint nec-plugin-test-coverage This commit refactors the base class of unit tests for NEC Plugin to make writing new tests easier. Add fake OFC Manager and change unit tests which use OFC Manager mock to using this fake. With this fake, we don't need to set return_value and side_effect to the mock instance of OFC Manager in each test case. This fake keeps all resources on OFC, and returns existence of resources properly. This fake is attached to OFC Manager mock instance by setting all side_effects. We can also set it to raise an exception. Make NEC Plugin configurable in each test case. Now we can configure NEC Plugin by setting string in class value "_nec_ini" which will be written into a temporal file and loaded by NEC plugin. Move setup for callbacks into NecPluginV2TestCase() so that other unit tests can use callbacks. Change-Id: I3a52423bb5813547345677dc49abfea6563dd6cd
