Offer an error returning version for some of the deployment and pod actions

[Skarlso]

They do a t.Fatal right now, which isn't always desirable as I would like to gather more information. And in case something doesn't exist or doesn't have pods, or cant' load anything, I don't care, go to the next deployment I'm trying to dump information from.

This would be possible by returning the error which I can then ignore. :) Or, don't do a fatal, but a t.Error and continue.
