Alex Behm 9d46853fbc Nested Types: Check un/supported file formats for complex types. ...

Before this patch, we used to accept any query referencing complex
types, regardless of the table/partition's file format being scanned.
We would ultimately hit a DCHECK in the BE when attempting to scan
complex types of a table/partition with an unsupported format.

This patch makes queries fail gracefully during planning if a scan
would access a table/partition in a format for which we do not
support complex types.

For mixed-format partitioned Hdfs tables we perform this check
at the partition granularity, so such a table can be scanned as
long as only partitions with supported formats are accessed.

HBase tables with complex-typed columns can be scanned as long as
no complex-typed columns are accessed in the query.
