    SOLR-????: tweak SearchHandler getDefaultComponents initial capacity (from 6 to 8)

commit 093859e77ee03ae2fee23ef4fc6941a119d5d135

    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
