In case of size limit exceeds during the check, CS will through resourceAllocation exception
right after the check and in case of failure of creating any snapshot or volume, CS decrements
the count accordingly.

I considered the volume which is created on secondary storage and this happens only if user
uploads a volume. If user attach this volume to any VM, it moves from secondary to primary,
so CS decrements secondary storage count and increment primary storage count.

We cannot wait for volume to get into READY state to increment the count because all these
calls are async and this will give user some time to create more volume/templates etc. which
may have out of his storage limits.

Sailaja has already shared the test case for this feature which covers all these scenarios.
