CLOUDSTACK-8896: allocated percentage of storage pool going beyond 100%This
issue occurs when a volume in Ready state is moved across storage
pools.
While finding if the storage pool has enough space, it has a check to
consider the size of non Ready volumes only. This is true if the volume
to be attached to a vm is in the same storage pool. But, if the volume
is in another storage pool and has to be moved to a vm's storage pool,
the size of the volume should be considered in doing the space check.
computing the asking size when volume is not in ready state or when the
volume is on a different storage pool.
Testing:
I couldnt write unittests for it. This class is not in a unittestable state.
manually tested in the below environment
1. xenserver 6.5 setup with 2 clusters and a host each in each of them.
2. added storage tags for the primary storage.
3. created two service offerings with the storage tags.
4. deployed two vms using newly created offerings in step 3.
5. at this stage, there are two vms one on each host with root disks on the
corresponding primary.
6. create a data disk and attach it to vm1
7. detach the data disk. now the data disk is in the primary storage of the
cluster of vm1 (let us say primary1)
8. attach this data disk to vm2(running on a host in different cluster)
9. the volume should be moved to the primary storage of another cluster and
op_host_capacity should be accordingly updated.

> This issue occurs when a volume in Ready state is moved across storage pools.
> Let us say there is a data volume, volume0 in Ready state in a cluster scope
> primary storage primary0.
> Now, when an operation is attempted to attach this volume to a vm in another
> cluster, the volume is moved to the new cluster and the asking size is zero
> at this time.
> you can observe logs like below with asking size 0 in the management server
> logs.
