Use v1 as default for cinder_catalog_info

In c5402ef4fc509047d513a715a1c14e9b4ba9674f we recently
added support for the Cinder v2 client. This change modified
the default value of the cinder_catalog_info config such
that an end user who was previously using the Cinder V1
API via the default config setting (by not setting it) would
have a broken Nova -> cinder configuration upon upgrade.

We should hold off on changing the default cinder_catalog_info
for one release to allow for proper deprecation.
