Bug 1220871 This patch does minimal changes in neutron.plugins.nicira.common.sync providing unit tests with a reference to the looping call object, so that they can control its lifecycle. Also, it perform a bit of refactoring in test_l3_agent.py in the way mocks are created and started. Change-Id: I73a1eb8ecdb7c6d46ff12afba549dd27095b7202
