---------------------------------------------------------------
Latest patch is a version of CloudSolrServer that:
1)Does document routing
2)Sends requests to each shard in a separate thread
3) Uses javabin transport
4) Is backwards compatible with both the response and exception.
It does this all by default, no switches needed.
This is accomplished by returning a response or throwing an exception that
condenses the info from each shard into a single response or exception.
To get the full info for the response or exception you can down cast to either
RouteReponse or RouteException which gives you a detailed breakdown from each
of the shards.
Will update the ticket name and description accordingly.

> This issue adds the following enhancements to CloudSolrServer's update logic:
> 1) Document routing: Updates are routed directly to the correct shard leader
> eliminating document routing at the server.
> 2) Parallel update execution: Updates for each shard are executed in a
> separate thread so parallel indexing can occur across the cluster.
> 3) Javabin transport: Update requests are sent via javabin transport.
> These enhancements should allow for near linear scalability on indexing
> throughput.
> Usage:
> CloudSolrServer cloudClient = new CloudSolrServer(zkAddress);
> SolrInputDocument doc1 = new SolrInputDocument();
> doc1.addField(id, "0");
> doc1.addField("a_t", "hello1");
> SolrInputDocument doc2 = new SolrInputDocument();
> doc2.addField(id, "2");
> doc2.addField("a_t", "hello2");
> UpdateRequest request = new UpdateRequest();
> request.add(doc1);
> request.add(doc2);
> request.setAction(AbstractUpdateRequest.ACTION.OPTIMIZE, false, false);
> NamedList response = cloudClient.request(request); // Returns a backwards
> compatible condensed response.
> //To get more detailed response down cast to RouteResponse:
> CloudSolrServer.RouteResponse rr = (CloudSolrServer.RouteResponse)response;
> NamedList responses = rr.getRouteResponse();
