Test/error on fail

[nicklesimba]

Added unit test for error-on-fail fix.

Proposed Changes

• Provided unit test for error-on-fail fix.
• Modified k8sclient.go, now uses ClientInfo as an interface and KubeClient as the struct that implements ClientInfo. This is to aid in the unit test, which uses a FakeKubeClient struct to implement ClientInfo.
