    SOLR-????: support creation of a coreless collection
    
    By supplying a deliberately empty create node set (via 
.../solr/admin/collections?action=CREATE&createNodeSet=&name=myCollection&...) 
the collection can be created in the usual manner but it will just not yet 
contain any cores for any of its shards. Later on 
.../solr/admin/collections?wt=json&action=ADDREPLICA&collection=myCollection&...
 calls can create cores as and when and where required.
    
    The change to suppport this small new feature is in 
OverseerCollectionProcessor.java and in TestMiniSolrCloudCluster a new test 
case (testCollectionCreateWithoutCoresThenDelete) was added.
