Time series refactoring & SQL / JDBC integration

[ambud]

Adding refactoring of time series internals to add true columnar storage with iterators and independent predicate push down. Adding Apache Calcite integrations with Avatica jdbc server for ANSI SQL queries on data.

New refactored time series reduces memory footprint by caching and reusing objects thereby allowing more series to be run on a smaller footprint machine. (360K unique series with 4M+ columns on 6GB heap and 16GB total memory)
