> Creating a collection with implicit router adds shard ranges to each shard.
> Using the Example A from SolrCloud wiki:
> bq. http://localhost:8983/solr/admin/collections?action=CREATE&name=myimplicitcollection3&numShards=2&maxShardsPerNode=5&router.name=implicit&shards=s1,s2&replicationFactor=2
> The following clusterstate is created:
> {quote}
> "myimplicitcollection3":{
>     "shards":{
>       "s1":{
>         "range":"80000000-ffffffff",
>         "state":"active",
>         "replicas":{
>           "core_node1":{
>             "state":"active",
>             "base_url":"http://192.168.1.5:8983/solr",
>             "core":"myimplicitcollection3_s1_replica2",
>             "node_name":"192.168.1.5:8983_solr"},
>           "core_node3":{
>             "state":"active",
>             "base_url":"http://192.168.1.5:7574/solr",
>             "core":"myimplicitcollection3_s1_replica1",
>             "node_name":"192.168.1.5:7574_solr",
>             "leader":"true"}}},
>       "s2":{
>         "range":"0-7fffffff",
>         "state":"active",
>         "replicas":{
>           "core_node2":{

>             "core":"myimplicitcollection3_s2_replica2",
>             "node_name":"192.168.1.5:8983_solr"},

>             "node_name":"192.168.1.5:7574_solr",
>             "leader":"true"}}}},
>     "maxShardsPerNode":"5",
>     "router":{"name":"implicit"},
>     "replicationFactor":"2"}
> {quote}
> Collections with implicit router should not have shard ranges at all. Note that the createshard
API does the right thing.
