Run `go fmt` or `gofumpt` against go code

[chrisseto]

We don't currently have any style enforcement of our go code. Let's start running go fmt or gofumpt within CI to enforce consistent styling and fix the occasional diff churn with all the +gotohelm annotations/markers.

It has been a while since i made changes to our CI, would like to use this ticket as an excuse to checkout out the current changes and start contributing here. You ok with this @chrisseto ?

Sure but let's try to work through our planned queue first? We can toss this in and push it a little bit up the stack but I'd like us to make a bit more progress on the go conversions.
