* [docs] Mounting config file in container
This adds a small section clarifying how to mount a config.yaml in a
container.
* [docs] Work in GTS_CONFIG_PATH
* [docs] Change configuration creation instructions
This changes the wording to push people towards creating their own

makes it much easier to reconcile necessary configruation changes on
upgrades.

what the risks of a moving tag are. It pushes people to use an explicit
release tag instead.
