Alistair Coles 252f0d36b7 proxy: only use listing shards cache for 'auto' listings ...

The proxy should NOT read or write to memcache when handling a
container GET that explicitly requests 'shard' or 'object' record
type. A request for 'shard' record type may specify 'namespace'
format, but this request is unrelated to container listings or object
updates and passes directly to the backend.

This patch also removes unnecessary JSON serialisation and
de-serialisation of namespaces within the proxy GET path when a
sharded object listing is being built. The final response body will
contain a list of objects so there is no need to write intermediate
response bodies with a list of namespaces.

Requests that explicitly specify record type of 'shard' will of
course still have the response body with serialised shard dicts that
is returned from the backend.
