Slightly updated tasks and added validation checks
1. Now does not remove prerequisite packages, lvm2 was included in these packages (not good when you use LVM2 for real). 2. Added a bit more idempotency to the shell scripts - only delete if it exists. 3. Check that the process isn't running and binaries are gone.
