IMPALA-12229: Support soft-delete Kudu table
Adds 'kudu_table_reserve_seconds' query option to set reserved time
for deleted Impala managed Kudu tables. The default value is 0.
This option can prevent users from deleting important Kudu tables
by mistake.
Testing:
- Added e2e tests.

> URL: https://issues.apache.org/jira/browse/IMPALA-12229
> Project: IMPALA
> Issue Type: New Feature
> Reporter: YifanZhang
> Priority: Major
>
> Kudu now supports soft-deleted tables (KUDU-3326). Users can specify a
> reservation period when soft-deleting a table via Kudu client API. Kudu then
> keeps the table aside for a period of time, not deleting the data
> immediately. The table can be recalled back before its reservation expires.
> Impala should support this feature when using DROP TABLE statement to remove
> Impala-managed(or internal) Kudu tables.
