Create slim version of release Docker images

[georgemccabe]

Describe the Task

• Create Docker images of releases that have some files removed. Start with removing internal files that are not actually needed by end-users, with a focus on files that may flag vulnerabilities. METplus use cases that do not conform to USAF OTTI standards could also be removed until they are made compliant. Once the process is in place, additional files and tools that are not actually used by the METplus software could also be removed as needed to reduce the size of the image.

• Create a dtcenter/metplus:6.2-slim image on DockerHub.

• Add the generation of the slim images to the GitHub Actions workflow that creates release Docker images so that future releases will have a slim version available.
