warlock 1.3 breaks glanceclient metadef models

[Steve McLellan]

Warlock 1.3 was released June 25 2016 and appears to break metadef handling via the v2 API in glanceclient. Partial stacktrace below; you can reproduce it with:

 # gc is a glance client instance
 metadefs = list(gc.metadefs_namespace.list())
 ns = metadefs[0]['namespace']
 gc.metadefs_namespace.get(ns)

Warlock <1.3.0 doesn't exhibit the issue.

Until this is resolved, searchlight indexing for metadefs will fail. To workaround, install warlock<1.3.0.

Should this be moved to bug 1596573 to keep it all in one place?

[Travis Tripp (travis-tripp)]

Done for searchlight.
