Ability to disable generation of "go:generate" comment in generated code

[jmcnevin]

Problem statement

It would be nice to be able to disable the creation of the go:generate comment inside of the default templates here. We find this conflicts with our CI flows more often that not.

Environment

version: v0.24.0
commit: 094421c

The configure API is generated only once and just sketches the init steps to run an API.
It is intended to be manually edited and customized. It is not regenerated when you run again the generation.
You may remove the go generate line.
