Description

How Has This Been Tested?

buildshiprun and garbage collect part of #609

I tested it on my local cluster using k3s and k3d for local development.

@Watetdrips please could you review?

[martindekov]

Hey Vivek, LGTM. Just wondering why we use fmt instead of log? I saw we use fmt in couple of places. Also commented out code can be removed if not used. Those are not blocking though so I approve 👍

[alexellis]

Approved, given the testing and approval from @martindekov
