Support for Elastic.Clients.Elasticsearch

[gregkalapos]

This PR is covering the rest of the things needed to support the new Elasticsearch .NET Client.

The core of the change was done directly in the client code: elastic/elasticsearch-net#6990

This PR adds:

• Integration-tests with docker by using the new es client and by using the OTel bridge in the agent.
• Implements suppression of HTTP span creation when elasticsearch spans are already created by the OTel bridge.

Regarding release: I think this should not block a release - if this ends up being merged after the next release, it's still fine.
