IIUC A Solrj 4.4 client should be able to speak to a Solr 4.6 cloud
instance.
Assuming this is correct there's an issue because of a change in
clusterstate.json:
In a 4.4 cloud server clusterstate.json would contain `router: "implicit"`
In a 4.6 cloud server clusterstate.json contains `router:
{"name":"implicit"}`.
Because of this a 4.4 solrj client will look up a router (in
DocRouter.java) using the key `{"name":"implicit"}` instead of just
`implicit`.
Is there a way around this that does not involve upgrading the solrj client?
