Remove the leading '#!/usr/bin/env docker agent run' shebang and
following blank line from all example YAML and HCL files, as the
config format is now self-documenting.
This removes a lot of the unused in-yaml env management.
This idea is to have a provider of env variables at the top, being used
all the way down.
This is not fully done yet but required some preliminary cleaning.
