cinder volume attachments are no longer available

[Gerry Buteau]

attachments_list seems to be unavailable in CinderVolume.yaml while building the resource definition. This functionality was originally added by the following change, but is now no longer working.

The attachments_list output from buildResourceDefinition was removed as part of:

For our Oracle database package, we do need this information.

The root of this problem appears to be some recent changes in HEAT involving resource/attribute caching. This may be why the murano volume attachment tests were failing originally.

In addition to the change ellen-batbouta mentioned, there will need to be a patch for the heat project that indicates that the attachments_list attribute should not be cached for cinder volumes:
