Now that we are python3 only, we should move to using the built in version of mock that supports all of our testing needs and remove the dependency on the "mock" package. This patch moves all references to "import mock" to "from unittest import mock". It also cleans up some new line inconsistency. Fixed an inconsistency in the OVSBridge.deferred() definition as it needs to also have an *args argument. Fixed an issue where an l3-agent test was mocking functools.partial, causing a python3.8 failure. Unit tests only, removing from tests/base.py affects functional tests which need additional work.
