Lyrical testing docker images

[mikaelarguedas]

Using templates from osrf/docker_templates#119

Same strategy as for Jazzy (#741) :

• Provide Lyrical docker images for the testing phase before official release
• Publish these images (based on the testing apt repo) to dockerhub
• not add them to CI
• not move the latest tag

At official Lyrical releaste time:

• regenerate the images pointing to the right repo
• move the latest tag
• submit to dockerhub for rebuild
• enable CI

Alternative to #876

Main differences:

• Do not mix rolling and lyrical changes
• Do not enable CI
• Do not move the latest tag

To increase probability of this being accepted / built on dockerhub over the weekend I'll merge this as is and address suggestion / improvements / alternatives in a follow-up PR

I was building a local checkout just to verify and it passed as you posted your comment, haha!

Thanks both. For the roll out of production we've been discussing pushing to main with the release candidate which would allow us to switch to the main version and be live got the official release.

Awesome, once the decision / change is in effect how would one be notified about it (this way we can make the change on this repo).

Hopefully we'd ping you but, the decision was not to do it in the end.
