Introduce receive.denyDeletes
Occasionally, it may be useful to prevent branches from getting deleted from a centralized repository, particularly when no administrative access to the server is available to undo it via reflog. It also makes receive.denyNonFastForwards more useful if it is used for access control since it prevents force-updating by deleting and re-creating a ref.
