Sanket SudakeandGitHub 2a43213387 Use Clientset interface instead of type for Fission/kubernetes clients (#2416)
Using interface makes it easy to create a fake client and unit test
a specific portion of the code. We should be able to more write unit
test and increase coverage of code with this change.
