The new 'refresh' element can override the default refresh operations
for a storage pool. The only currently supported override is to set
the volume allocation size to the volume capacity. This can be specified
by adding the following snippet:
<pool>
...
<refresh>
<volume allocation='capacity'/>
</refresh>
...
</pool>
This is useful for certain backends where computing the actual allocation
of a volume might be an expensive operation.
