Ok, I've reverted everything I believe. Bummer. I need to think about how to get this released now.

> This ticket provides support for executing *Parallel SQL* queries across SolrCloud collections. The SQL engine will be built on top of the Streaming API (SOLR-7082), which provides support for *parallel relational algebra* and *real-time map-reduce*.
> Basic design:
> 1) A new SQLHandler will be added to process SQL requests. The SQL statements will be compiled to live Streaming API objects for parallel execution across SolrCloud worker nodes.
> 2) SolrCloud collections will be abstracted as *Relational Tables*.
> 3) The Presto SQL parser will be used to parse the SQL statements.
> 4) A JDBC thin client will be added as a Solrj client.
> This ticket will focus on putting the framework in place and providing basic SELECT support and GROUP BY aggregate support.
> Future releases will build on this framework to provide additional SQL features.
