Subject: Added numerous improvements to our Docker image. (#10308)

* Initial cleanup of Docker entrypoint script.

* Add linting for our Docker files.

* Fix warnings reported by hadolint.

* Add support for automatic claiming on startup.

* Optimize Docker image structure.

This shuffles some things around in the Docker image to cut down on the
total number of layers and make the image more caching friendly, which
will cut down on overall time required to both initially pull the image
and time spent pulling updated versions of the image.

It also shrinks the image size by about 2MB.
