Remove Unused Job Builder Scripts

[doks5]

What is the feature request? What problem does it solve? Currently, there are two job builder directories in the Control Service project, one which is used, https://github.com/vmware/versatile-data-kit/tree/main/projects/control-service/projects/job-builder , and another one, which is DEPRECATED, https://github.com/vmware/versatile-data-kit/tree/main/projects/control-service/projects/vdk_job_builder.

This may confuse new contributors, who are not familiar with the project, and lead them to make changes to the wrong directory.

Suggested solution Remove unused job builder directory and scripts.
