Remove mapping types

[dreamer-89]

As part of v2.0 release, mapping types are getting removed from OpenSearch engine. Below are the changes in the opensearch-engine.

• Removal of type from rest end-points
• Removal of include_type_name parameter from API requests.

As part of this issue, please verify if type removal change on OpenSearch engine impacts this repository. If yes, then please remove the type references/usage from this plugin.

Data Prepper is not using mapping types.

The mapping files do not have types defined:

• https://github.com/opensearch-project/data-prepper/blob/main/data-prepper-plugins/opensearch/src/main/resources/otel-v1-apm-span-index-template.json
• https://github.com/opensearch-project/data-prepper/blob/main/data-prepper-plugins/opensearch/src/main/resources/otel-v1-apm-service-map-index-template.json

Search results are empty:

Additionally, I verified the indices in an OpenSearch cluster do not have custom types.

I removed the 1.4 milestone. Data Prepper was not using mapping types prior to 1.4. I also checked the history and the index templates have no indication of ever using mapping types.
