Add support for IOT tables

[bersler]

Is your feature request related to a problem? Please describe.
IOT tables are not supported.

Describe the solution you'd like
Sometimes a schema needs to be replicated that uses an IOT table and the schema cannot be changed. OLR should also support such cases.

Describe alternatives you've considered
Change the schema to non IOT. Maybe some trigger solutions. But generally there is no good solution available.

Additional context
This requires support for additional redo log op codes, since part of the data can be stored in index vector data. Additionally overflow IOT tables should be fully supported as well.

If there is demand from business to support this feature, it should be added.
