> h2. Description
> It was noticed that expunging instances with many vm snapshots took a look of 
> time, as hypervisor received as many tasks as vm snapshots instance had, 
> apart from the delete vm task. We propose a way to optimize this process for 
> instances with vm snapshots by sending only one delete task to hypervisor, 
> which will delete vm and its snapshots
> h2. Use cases
> # deleteVMsnapohsot-> no changes to current behavior
> # destroyVM with expunge=false ->  no actions to VMsnaphsot is performed at 
> the moment. When VM cleanup thread is executed it will perform the same 
> sequence as #3. If instance is recovered before expunged by the cleanup 
> thread it will remain intact with VMSnapshot chain present
> # destroyVM with expunge=true:
> #*       Vmsnaphsot is  marked with removed timestamp and state = Expunging 
> in DB
> #*       VM is deleted in HW
