Re-enable focal and attempt to use tooling images

[mjcarroll]

Re-enable continuous integration on focal.

This also makes use the docker container actions that are set up here: https://github.com/ignition-tooling/setup-ign-docker

Those containers pre-install all of the dependencies found in a particular collection, which should accelerate CI a little bit.

Thanks for remembering that Focal CI needs to be re-enabled! I think that we also need to fix all the Focal warnings / tests.

This also makes use the docker container actions that are set up here: https://github.com/ignition-tooling/setup-ign-docker

Mind adding some information to that repository's README? It's hard to know what it's doing without digging through the code.

One thing I'm wondering about is how often these images are updated. For example, if we made a release 1 hour ago, will it be picked up?

Yep! Can do.

Edit: gazebo-tooling/setup-gz-docker#3

They are currently built hourly. There is a chance that a release could be missed, but it should be picked up in the next build.

Edit: Now that I think about this, because we do an apt update && install in the action itself, it should pull the newest dependencies during that step.

Regular Focal CI was added in #646 and is being ported forward in #792. Once that's in, this PR can be updated to just use the tooling images (no need to handle the addition of Focal).

[chapulina]

Is there a way we can skip this step? Can the container be publicly available, or shared with the ignitionrobotics org? This way, we just need to update the action-ignition-ci repository and don't need to add this step to all branches of all libraries.
