[FEATURE]: Bulk Index (IndexOperation) should support opType attribute

[workmanw]

Is your feature request related to a problem?

The IndexRequest supports opType, however the IndexOperation class does not. It should.

What solution would you like?

I would like to see opType as an attribute on the IndexOperation builder and class.

What alternatives have you considered?

N/A

Do you have any additional context?

I would be happy to implement this if there are no concerns from the maintainers.

@reta @Bukhtawar @szabosteve @madhusudhankonda maintainers please take a look

@workmanw the Bulk APIs support IndexOperation (equivalent to OpType::Index) and CreateOperation (equivalent to OpType::Create) explicitly, whereas IndexRequest is part of Indexing API and was designed differently

🤦‍♂️ Sorry about that.

Thank you @reta for the clear explanation.
