Feat/optional-istio - Ignore the Istio process in the beginning

[knmsk]

Added a way to ignore the scuttle inside starter and runner.

edit: Build off of #49, #53 and #54

Overall, I like this. Two general comments:

1. Should we put the ENV variables for scuttle behind a bool as well? This would prevent unnecessary ENV or edge case interactions. But might be a big pain.

2. Composition wise. Should we move the istio check into the helpers.go and let it return a command and env variables? So we can keep everything in the same place?

Probably it's better to create a struct for this stuff.

Sure, we can move into the helpers.go it makes sense!
