Update DAST release scripts
All threads resolved!
The Secure Report Format schema heavily borrows from the DAST release scripts. As another round of reviews occurred on these scripts, the code quality was greatly improved. This MR merges these changes back into the DAST repository.
There is also a requirement for DAST Docker images to be released to the analayzers/dast Docker registry. This will make it easier for offline GitLab setups to download all of GitLab Secure images. The ability to deploy to more than one registry is also included in this MR.
