Option for collapsing jcr:content nodes doesn't work in embedded Solr

When enabling collapseJcrContentNodes in the Solr index configuration while using an embedded server, querying will fail because of an unsatisfied dependency (com.carrotsearch.hpc which is ~1.3MB) in oak-solr-osgi pom.xml.
The mentioned dependency should be added to oak-solr-osgi pom in order to make it possible to use that option with embedded server too.
