Title: Work around failed CDN metadata lookups with HPCS

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. When HP improves their CDN support we should remove this
workaround.
