[PROPOSAL]Merge opensearch-dsl-py into opensearch-py repository

[saimedhi]

What/Why

What are you proposing?

Merging opensearch-dsl-py features completely into opensearch-py without having separate repo or folder.

What users have asked for this feature?

reference- issue 194 opensearch-py

What is the user experience going to be?

The user experience would be unchanged from how it is today, however it will make developer experience much better. Maintainers will have to release and maintain only one client instead of both opensearch-py and opensearch-dsl-py.

Any remaining open questions?

This proposal is open for discussion. Kindly comment your opinions in the issue reference above.
