Extra GIT_STRATEGY none-clean

It would be helpful to get a new GIT_STRATEGY which results in running the job in a clean/empty folder instead of in a folder which contains the runner-cache of the last job/pipeline.

Today we use GIT_STRATEGY: none for deployment jobs, in these jobs we have dependencies to build jobs who make artifacts with a version number, next when you run the deploy job on a shell/powershell/cmd runner (but also on docker runner) you will see that you have artifacts of different pipelines.
