Fixing shellcheck warnings in anago

[pswica]

Please see: #742 and #726 for more details and context.

I found one variable that shellcheck warned about not being used (type: 869). Let me know if these should be added back in due to some kubernetes release magic. Also let me know anything else to improve on :)
