Add a new flag to cleanup the filesystem at the end

Browse Source 
Currently, kaniko can only build a single image per container run, because the filesystem is full of the content of the first image.
When running kaniko in Jenkins, where we need to start the container "doing nothing" first (using the debug kaniko container), and then exec /kaniko/executor, this is a limitation because it means that if we want to build multiple images, we need to start multiple containers - see https://groups.google.com/forum/#!topic/kaniko-users/_7LivHdMdy0 for more details

A solution to fix this issue is to add a new flag to cleanup the filesystem at the end - the same way it is done between stages when building a multi-stages image. This way, the same (debug) container can be used to build multiple images.
