boot from volume fails when upgrading using cinder v1 API

[Dan Prince]

In c5402ef4fc509047d513a715a1c14e9b4ba9674f we added support for the new cinder V2 API.

When a user who was previously using the Cinder v1 API (which would have been required) updates to the new code the immediate defaults cause the cinder v2 API to be chosen. This is because we now default cinder_catalog_info to 'volumev2:cinder:publicURL'. So if a user was using the previous default value of 'volumev2:cinder:publicURL' their configuration would now be broken.

Given the new deprecation code hasn't been released yet I think we need to wait at least one release before we can make this change to our cinder_catalog_info default value.

This is the exception you'll see if your Keystone endpoint still uses the Cinder V1 api and you upgrade to the latest nova code:

    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.
