This MR introduces the new script for Superbuild continuous integration.
As SuperBuild is provided by OTB we need to test is, and to test OTB with its dependencies coming from Superbuild.
The job is a two folds job. First we check that there is an available superbuild (meaning build from the current sources) if not we build it and push it on a different repository.
Then we build OTB with the corresponding SuperBuild.
