Handle elasticsearch client native instrumentation

[xrmx]

Describe your environment

Elasticsearch client added native opentelemetry instrumentation in 8.13.0 and so currently without manual intervention it is possible to have our instrumentation and the client one create spans concurrently.

Steps to reproduce

Add opentelemetry instrumentation using elasticsearch client 8.13.0

What is the expected behavior?

Only the elasticsearch client creates spans.

What is the actual behavior?

Both client and opentelemetry instrumentation creates their own spans.

Additional context

Java opentelemetry instrumentation disables its instrumentation if a new enough elasticsearch client is found https://github.com/open-telemetry/opentelemetry-java-instrumentation/pull/9337/

Since we are hooking into transport perform_request we can check if one of its kwargs is otel_span (https://github.com/elastic/elasticsearch-py/blob/main/elasticsearch/_sync/client/_base.py#L271) and if its enabled attribute is True (https://github.com/elastic/elasticsearch-py/blob/main/elasticsearch/_otel.py#L46).

Before fixing this we need to make tests pass with elasticsearch 7 and 8
