Build images using Github Actions

### Description

* Builds are currently done by the maintainer

### Solution

* Builds should be automated using Github Actions

### Steps to Reproduce

1. Use actions to build and push docker images by reusing the `tools/*` scripts
* Github Actions example at https://github.com/marcellodesales/gitman-docker/commit/5e6d37b824a08da12a41eca06bc4bba808eda759/checks
2. Make the steps to be push all the images to Docker Registry

Start by reviewing the existing tools/* scripts and the referenced GitHub Actions example to understand how images are built. Define the workflow steps needed to reuse those scripts and push all images to a Docker Registry; done means builds no longer require the maintainer to run them manually.
