CS-50190:CLONE - Simultaneous snapshots for detached volume
Description
A detached volume on any hypervisor (Xen, Vmware, KVM) fails to create one of the snapshots if it there are two scheduled snapshots at the same time for the same volume. One of that goes to Allocated state. any combination of weekly,daily and hourly simultaneous snapshot creation on a detached volume results one of the snapshots in Allocated state forever which can not be deleted
Solution
For detached volume, when two simultaneous snapshots are requested, one will be successfully created and other snapshot will get executed in next snapshot scheduler run. Thus all the simultaneous snapshot request will be completed with time difference of snapshot scheduler polling.

@mrunalinikankariya Can you provide some marvin test? Also is it possible to add some snapshots/test results?
