Is your feature request related to a problem? Please describe.

Currently elasticsearch exporter uses go-elasticsearch v7 because of the "forward compatibility" described in https://github.com/elastic/go-elasticsearch?tab=readme-ov-file#elasticsearch and raised in #16310. However, this means that v8 stack users are also forced to use go-elasticsearch v7 as mentioned in #29689. v8 go-elasticsearch client gets the bugfixes and features that may not be available in v7 go-elasticsearch client. Elasticsearch exporter should support both v7 and v8 elasticsearch client, and ideally default to v8 (which may be a breaking change).

Describe the solution you'd like

• Support both v7 and v8 go-elasticsearch client and expose it as a configuration option.
• Default to v8 client

Describe alternatives you've considered

Still relevant, and this should be ready to implement as elasticsearchexporter is now using go-docappender
