Description

Several built-in adapters (MongoDB, JDBC, TPCH, TPCDS, Clone, Splunk, MetaImpl.MetadataTable, ViewTable) use QueryableTable (and AbstractQueryableTable) for their tables. Therefore they are forced to do code-generation in their plans, and they depend on the enumerable adapter (which we want to move into a separate project).

This task would remove those dependencies. A lot of these could use ScannableTable, FilterableTable or ProjectableFilterableTable.
