Added CICD dry run

This is the first attempt at setting up a dry run pipeline
to test changes to the CICD config without actually publishing
the compiled binaries and packages built by the process.

The dry run should be triggered by any changes to .gitlab-ci.yml
or changes to any of the scripts under scripts/cicd/.

.gitlab-ci.yml
