Visual log parsing and data loading with Streaming Expressions

      Streaming Expressions and Math Expressions are now mature on the query side. This includes the ability to query, transform, analyze and visualize data. 

      It's now time to build the data loading and log parsing capabilities to apply the full suite of mathematics and visualizations over log data and CSV files.

      The design is to have stream sources that read from a file system and stream decorators that parse different file and log formats. The data can be further transformed and joined with other data by stream decorators and sent to any Solr Cloud collection with the update Stream.

      This design also allows Streaming Expressions to perform regex filtering, aggregations, statistical analysis and visualization directly over CSV files and log files before the data is loaded to Solr. Because of Streaming Expressions built in paralyzation capabilities this allows Solr Cloud to behave like a massively parallel grep engine. 

      It also allows users to visualize data using Apache Zeppelin as part of loading process, to make it easier to understand the data before it's loaded into an index.

      This ticket will track the sub-tickets for the different log formats that will be supported.
