Try out dynamic mapping in OpenSearch v2

[yuanzhou]

Note: Chris will help create a new OpenSearch v2.11 domain on AWS for Dev/test use.

When index a document, OpenSearch adds fields automatically with dynamic mapping, we can explicitly specify field types on certain fields. Find out the following:

• Does the OpenSearch dynamic mapping still works fine based on the current mapping settings created for Elasticsearch 7.10?
• Can we rely on dynamic mapping without explicit mapping rules on fields with inconsistent data types?
• Any additional index mapping or setting changes are needed to work with OpenSearch v2.11?

Our current mappings and settings:
