Bug #79789 DATA/INDEX DIRECTORY are not in information_schema.TABLES

Description:
Table options are stored in information_schema.TABLES. For example, MAX_ROWS is stored in the TABLE_OPTIONS column, and ENGINE is stored in the ENGINE column. But DATA DIRECTORY and INDEX DIRECTORY table options are not stored in any column.

I originally reported this bug to MariaDB, then I was told that it is an upstream bug:
https://mariadb.atlassian.net/browse/MDEV-9307

How to repeat:
Search the I_S for that information.

Suggested fix:
Add that information to the CREATE_OPTIONS column.

Please check if in the create table command you get warnings if yes please print here. Check also if applied with https://bugs.mysql.com/bug.php?id=77773 as duplicate. Thanks.

Forgot to paste:

Maybe you are running with symbolic links disabled, this would make the options be ignored. 

Bug #77773 is different, it's specifically about partitioned tables, while this one has nothing to do with partitions.

I've provided the link to the test case... but maybe Oracle ignored it because it contains the word "MyISAM", so I'll adapt the test case to InnoDB:

mysql> USE test;
Database changed
mysql> CREATE TABLE t (c INT) ENGINE = InnoDB, ROW_FORMAT = REDUNDANT, DATA DIRECTORY = '/tmp';
Query OK, 0 rows affected (0.02 sec)

mysql> SELECT CREATE_OPTIONS FROM information_schema.TABLES WHERE TABLE_SCHEMA = 'test' AND TABLE_NAME = 't';
+----------------------+
| CREATE_OPTIONS       |

I used the default configuration file and got no warnings.

Thank you for the feedback. 5.5/5.6/5.7 affected.
