I'd like you to reexamine a change. Please visit

to look at the new patch set (#4).

Change subject: IMPALA-10288: Implement DESCRIBE HISTORY for Iceberg tables
......................................................................

IMPALA-10288: Implement DESCRIBE HISTORY for Iceberg tables

The DESCRIBE HISTORY works for Iceberg tables and displays the
snapshot history of the table.

An example output:
DESCRIBE HISTORY iceberg_multi_snapshots;
+----------------------------+---------------------+---------------------+---------------------+
| creation_time              | snapshot_id         | parent_id           | 
is_current_ancestor |
+----------------------------+---------------------+---------------------+---------------------+
| 2020-10-13 14:01:07.234000 | 4400379706200951771 | NULL                | TRUE 
               |
| 2020-10-13 14:01:19.307000 | 4221472712544505868 | 4400379706200951771 | TRUE 
               |
+----------------------------+---------------------+---------------------+---------------------+

The purpose here was to have similar output with this new feature as
what SparkSql returns for "SELECT * from tablename.history".
See "History" section of
https://iceberg.apache.org/spark/#inspecting-tables

Testing:
  - iceberg-negative.test was extended to check that DESCRIBE HISTORY
    is not applicable for non-Iceberg tables.
  - iceberg-table-history.test: Covers basic usage of DESCRIBE
    HISTORY. Tests on tables created with Impala and also with Spark.
