Traefik image config for version pinning, upgrades, and custom images

Browse Source 
Accounts for the 2.9.10 security release and allows testing Traefik 3 betas.

* Use `image` to configure a specific Traefik Docker image.
* Default to `traefik:v2.9` to track future 2.9.x minor releases rather
  than tightly pinning to `v2.9.9`.
* Support images from the configured registry.
