Execute unit tests for Cisco plugin with Quantum tests

Bug #1041917

On account of the new requirement to run plugin-specific tests also
along with the Quantum tests, changes are being made to
incorporate the Cisco plugin unit tests into the Quantum unit test
suite. Earlier unit tests have been moved and modified.
