Jenkins administrative groovy scripts

Make slave cleanup (destruction) groovy scripts accessible to anyone
that has script console access in Jenkins. Mostly this is just me
publishing the scripts so that Thanh has access and Google picks them up
when it indexes our mirror for others that may run into similar problems
that we have when trying to cleanup slaves that are not cleaning up
properly.
