[orenccl]

What changes were proposed in this pull request?

Add --index option to display index information on Tables.

Fix TableDetails command.

Update cli/README.md for table commands

Why are the changes needed?

This change allows users to retrieve additional index information on Tables, providing more insights.

Fix: #5277

Does this PR introduce any user-facing change?

Yes, it adds the --index option to CommandEntities.TABLE.

How was this patch tested?

1. Follow the instructions in the cli README to build the CLI sub-project.
2. Start the Gravitino Playground.

To test, use a command like the following:

gcli -i table details --metalake metalake_demo --name catalog_mysql.db.iceberg_namespace_properties

gcli -i table details --metalake metalake_demo --name catalog_mysql.db.iceberg_namespace_properties --index

gcli -i table details --metalake metalake_demo --name catalog_postgres.hr.employee_performance

Check that the output matches the expected audit information.

Thanks for the PR. For it to be consistent with other commands, I would output in CSV format with an index (and its type) on each line.

Hi @justinmclean

This is also done!

[jerryshao]

My question from another PR (#5525 (comment)), why do we need a new option to display the index information, can we just display all the table metadata information in one details command?

See #5525 (comment)

@jerryshao can we move forward on this?

@jerryshao can we move forward on this?

I've left the comment in another PR, I'm +0 on the current design choice, but I don't want to block things.

Thanks for your contribution

@jerryshao can you approve this? I approved this but I can't merge it.
