Title: Work around failed metadata lookups with Rackspace

Previously BlobStore.list and thus BlobStore.clearContainer serialized
on synchronous and failed CDN lookups. This effectively prevents
clearing any large container. We cache a negative entry to work
around this. This commit is similar to commit 3c7b965 to
hpcloud-objectstorage.
