Improve unit test coverage for Cisco plugin common code
Closes-Bug: #1190615 This fix improves the unit test coverage for the Cisco Nexus plugin common modules (directory neutron/plugins/cisco/common) from: --- cisco_credentials_v2.py 82% --- cisco_faults.py 0% --- config.py 84% To: --- cisco_credentials_v2.py 100% --- cisco_faults.py 76% --- config.py 100% Change-Id: Id1ccfee1317309039fab83f622ced58efc3b2ae7
