IMPALA-10456: Implement TRUNCATE for Iceberg tables
This patch adds support for the TRUNCATE statement for
Iceberg tables.
The TRUNCATE operation creates a new snapshot for the target
table that doesn't have any data files. Table and column stats
are also cleared. This patch also fixes a bug that caused
table/column stats not being propagated.
Testing
* added e2e tests for both partitioned and unpartitioned tables
