Add simple scripts to run generators for CI

This adds a couple of very simple scripts to run though the known outputs in the Connector and Nolead directories.

Then add it to the .gitlab-ci.yml CI pipeline definition file to be executed on a new MR.

This allows to verify that a given change at least doesn't prevent a generator running (more tests are required to ensure correctness, obviously!)

If this is an agreeable method I can extend to run other generators.
