Support for Elasticsearch 8.x

[sylvainOL]

Describe the bug

Today Spark dependencies only work with elasticsearch 7.x

To Reproduce Steps to reproduce the behavior:

1. install elasticsearch 8.x
2. launch spark dependencies

we have this in logs:

Exception in thread "main" org.elasticsearch.hadoop.EsHadoopIllegalArgumentException: Cannot detect ES version - typically this happens if the network/Elasticsearch cluster is not accessible or when targeting a WAN/Cloud instance without the proper setting 'es.nodes.wan.only'

Expected behavior It would be nice to make it work with ES 8.x (Jaeger is "supporting" it)

Version (please complete the following information):

• OS: Linux
• Jaeger version: 1.31
• Deployment: Kubernetes

Additional context

maybe by using this in pom.xml:

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch-spark-20_${version.scala.binary}</artifactId>
    <version>8.2.3</version>
</dependency>

For those of you who want to use this with elastic 8, here is the repo with the artefact built using the PR of @sylvainOL => https://github.com/vmaleze/spark-dependencies-es8/pkgs/container/spark-dependencies-es8 Unfortunately, the tests fails on the latest-jaeger stage and I have issues testing this on arm64. So I cannot fix it to submit a PR and merge this in the official repo. However, the forked repo works like a charm for elastic 8.
