> 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
