- [x] This PR:
- Adds docker tags for prebuilt builder images to the build docker-compose.yml
- is not related to any issue<!-- You can check for an issue here: https://github.com/apache/trafficcontrol/issues -->
Right now, building the RPMs requires first building the builder images, which takes 8.67 minutes on my Linux machine but almost certainly longer on MacOS. Since the builder images are mainly just yum installs, we can use prebuild Docker images without losing flexibility in terms of the code in each component.
Besides time saved, the other benefit of using prebuilt builder images is that CI pipelines would no longer fail in cases where installing yum packages fails.
I left the `build` fields in the docker-compose.yml for cases where someone wants to test a new builder image (e.g., new Go version).

> Ideally, we would have a jenkins job in place that rebuilds and updates the builder images every time a commit is merged to master.
Docker Hub does this by default (and I just re-enabled it). Note that the build statuses are viewable under the :heavy_check_mark: or :x: [in the list of commits](https://github.com/zrhoffman/trafficcontrol/commits/master).
You can also make it build for Git refs that match a certain regex.
As you say, triggering webhooks with Jenkins would work, too.

So, I'm kinda torn here, because I think this would be good, but it worries me that we don't really have an official supported process/automation for updating the builder images in the docker hub. Ideally, we would have a jenkins job in place that rebuilds and updates the builder images every time a commit is merged to master. Maybe we would also need images per official release (e.g. 4.0.x, 4.1.x, etc).
