  1. Move stale metadata check inside shard_for 

    metadata_cache.contains() is a slow call with many partitions becase
it scans the entire parition list looking for the specified one.

On the fetch planning path we can avoid this cost simply by
moving the check inside a shard_for check we do immediately
after the metadata check: in a stable system the shard_for check will
fail any time the metadata call will fail.
