1:M connectivity

[Oded Sofer]

Given that the index are always routed to specific machine, is there a way to 
avoid connectivity from the node to all other node. 
We are using Solr 4.10; the Add/Update Index uses SolrCloud API and always 
added to the node that get API request for add-index (i.e., we are sending the 
add index to the appropriate node that should get it).
