Proxy: restructure cached listing shard ranges
Updating shard range cache has been restructured and upgraded to v2
which only persist the essential attributes in memcache (see
Related-Change). This is the following patch to restructure the
listing shard ranges cache for object listing in the same way.
UpgradeImpact
=============
The cache key for listing shard ranges in memcached is renamed
from 'shard-listing/<account>/<container>' to
'shard-listing-v2/<account>/<container>', and cache data is
changed to be a list of [lower bound, name]. As a result, this
will invalidate all existing listing shard ranges stored in the
memcache cluster.
