new:dev:Upgrade Apache Calcite to 1.13 (#95)

The main changes are:

* JDBC uses Avatica 1.10. The interface has changed a bit and code had to be copied over.
* Parser required more APIs to be defined. These are empty for Quark.
* Calcite Core has changed processing of Materialized Views and Cubes.

One major change is that it expects the RowType of Cubes to as per an algorithm. 
Since Quark uses grouping_id to store a cube in the same table, the RowType of a 
QuarkTileTable does not match the expected RowType, QuarkTileTable now return 
TileScan -> Filter (GroupingId) -> Project. The new plan required changes in 
AggStarRule and FilterAggRule including changing ordinals.

RelOptToSqlConverter by default returns non-qualified names. Since Quark requires fully 
qualified names, QuarkTable has a pointer to QuarkSchema. This change required interface 
changes and subsequent changes across all derived classes.

As part of clean up, a few bugs were unearthed. These have been fixed.

A few tests have been ignored mainly in MaterializedViewsJoinTest. It looks like these were 
badly setup tests.
