Prepare the plugin to an elasticsearch 7.17.24 upgrade

[garaud]

Description

Upgrade the plugin with a more recent 7.17.x Elasticsearch version.

Changes

• Change the elasticsearch version to 7.17.24

• Update the build.gradle adding this kind of line

  tasks.named("yamlRestTest").configure {
    systemProperty 'tests.security.manager', 'false'
  }
  

  in order to avoid the test compilation failure java.lang.RuntimeException: unable to install test security manager

• upgrade Gradle to 8.10.2 (the previous 7.5.1 version raised an exception on the check task with an error which looked like java.lang.NoSuchMethodError: 'org.gradle.api.services.internal.BuildServiceProvider org.gradle.api.services.internal.BuildServiceRegistryInternal.consume(java.lang.String, java.lang.Class)')

• add some content to the README file

How to reproduce

Install Java 17. I suggest you to use sdkman tool which can help you to install any JVM for several languages (Kotlin, Java, Clojure, ...).

If you have an old build, I can also suggest you to remove the Docker image related to the elasticsearch-plugin-debug container and also remove the local .gradle folder.

If you use sdkman and you installed for instance 17.0.12-tem (OpenJDK by Eclipse Temurin)

• skd use java 17.0.12-tem
• ./gradlew build which compiles the code and run the tests
• docker compose up
• you should see a geopoint-clustering-aggregation-7.17.24.0.zip in the folder build/distributions
