Set volume.catalog_type to volumev3

This patch in tempest changed the default value of the catalog_type
for the cinder service to block-storage [1]. In RHOSO however, we
seem to be still using volumev3.

This patch ensures that the default value in ci-framework deployed
environment is still volumev3.
