Build and deploy Superbuild archive in CI
The Superbuild archive can be built with the SuperBuild-archive
cmake target from otb project. This target download source archives for all the Superbuild dependencies and create the super-archive.
Right now a script is in charge of building this target nightly. It would be better if it was CI that was in charge of building and deploying this archive. Instead of a nightly build it could be done in the deploy stage of the OTB pipeline, when pushing code to develop and release-X.X
Also the CMake fails silently in case of error (network error, error 404 on a dependency), and the archive is not created. We sould rework the script to make it more robust.
