Change in ovirt-engine[master]: core: remove memory snapshot when its not needed

Omer Frenkel has submitted this change and it was merged. Change subject: core: remove memory snapshot when its not needed ...................................................................... core: remove memory snapshot when its not needed This patch adds the removal of memory snapshot volumes in case it's not needed anymore: 1. when removing VM that has snapshots with memory 2. when snapshots with memory are removed because we revert (commit) to previous snapshot 3. on run VM when the VM reach to a point where the disks might not be synchronous with the memory state that was restored anymore (and the active snapshot is the only one that points to its memory) This patch also treat the restoration of snapshot's memory when running a VM that is previewing/being committed to a snapshot with memory in stateless mode.
