Adding config to SolrCloud without creating any shards/slices

[Per Steffensen]

Hi

We want to create a Solr config in ZK during installation of our 
product, but we dont want to create any shards in that phase. We will 
create shards from our application when it starts up and also 
automatically maintain the set of shards from our application (which 
uses SolrCloud). The only way we know to create a Solr config in ZK is 
to spin up a  Solr with  system properties zkHost, bootstrap_confdir and 
collection.configName. Is there another, more API-ish, way of creating a 
Solr config in ZK?
