> For legacy master/slave clusters, there is no Zookeeper to keep track of all the nodes
and shards in the cluster. So users manage the 'shards' parameter manually for distributed
search. This issue will add the option of configuring a list of what shards can be requested.
> Users will then get an explicit error response if the request includes a shard which
is not in the preconfigured whitelist, e.g. due to a typo. I think all shards logic is handled
by HttpShardHandler already so the logic should fit nicely in that one class, configured in
{{solr.xml}}.
