SOLR-????: reduce SearchHandler's overall use of ShardHandler objects (from
N+1+x to just 1)
before:
* A search request to an N-shard system constructs at least N+1
ShardHandler objects in total, 1 object in the receiving solr instance and 1
object in each of the N shards that receive sub-requests.
after:
* A search request to an N-shard systems constructs 1 ShardHandler object
in the receiving solr instance only.
summary of change:
* move non-distrib related code fragments from
HttpShardHandler.checkDistrib to SearchHandler
* rename ShardHandler.checkDistrib to ShardHandler.prepDistrib (to be
called for distributed requests only)
* SearchHandler constructs ShardHandler object only for distributed
requests
