From: Paulo Vital <pvital(a)linux.vnet.ibm.com>
With the new structure of Wok and Kimchi, the content of the objectstore file
needs to be updated to reflect the new paths of icon and storagepool present
in template's and VM's information.
This patch adds a script to execute an update of these contents in the
objectstore file during an upgrade from Kimchi 1.5.1 (or previous versions)
to the new Wok and Kimchi 2.0 (or earlier) RPM's.
