IMPALA-2890: Support ALTER TABLE statements for Kudu tables

With this commit, we add support for additional ALTER TABLE statements
against Kudu tables. The new supported ALTER TABLE operations for Kudu are:
- ADD/DROP range partitions. Syntax:
    ALTER TABLE <tbl_name> ADD [IF NOT EXISTS] RANGE <kudu_partition_spec>
    ALTER TABLE <tbl_name> DROP [IF EXISTS] RANGE <kudu_partition_spec>
- ADD/DROP/RENAME column. Syntax:
    ALTER TABLE <tbl_name> ADD COLUMNS (col_spec, [col_spec, ...])
    ALTER TABLE <tbl_name> DROP COLUMN <col_name>
    ALTER TABLE <tbl_name> CHANGE COLUMN <old> <new_name> <type>
- Rename Kudu table using the 'kudu.table_name' table property. Example:
  ALTER TABLE <tbl_name> SET TBLPROPERTY ('kudu.tbl_name'='<new_name>'),
  will change the underlying Kudu table name to <new_name>.
- Renaming the HMS/Catalog table entry of a Kudu table is supported using the
  existing ALTER TABLE <tbl_name> RENAME TO <new_tbl_name> syntax.

Not supported:
- ALTER TABLE <tbl_name> REPLACE COLUMNS
