Prepare plugin for Elasticsearch 7.17.20

[rprodan]

@vhyza I bumped dependency versions for making it compatible with Elasticsearch 7.17.18.

@vhyza when do you expect to be able to prepare a release? I'm happy to help if anything else is needed. Thank you.

Hi @rprodan,

to be honest I really don't know. For almost a year I didn't find the time/energy to make a new release so it accumulated quite a lot and now it is quite discouraging to even begin.

So I'd like to address first PR from @crabhi which could help with automatic builds and another PR from @vit-zikmund to simplify the dependencies a little bit.

The problem is that I need to try this on both master and elasticsearch-7 branches as Elastic is still releasing 7.x versions. Also, I changed a computer and now I see that the tests are not working (as mentioned in the PRs above) which is weird as they worked on the old computer 🤷‍♂️.

I do not think I'll be able to address this PR in the following days or weeks. If you need the packaged .zip I suppose I could upload it here when I'm able to run the tests. But I'm on arm64 (as a non-java programmer I do not know if it would work or not)...

I'm sorry I do not have better news...

@vhyza thank you for your answer. I completely understand you. If you need any help with this work please let me know. Regards, and keep good energy/spirit. 👍

@vhyza the issue with tests were the following dependencies

<dependency>
      <groupId>org.apache.logging.log4j</groupId>
      <artifactId>log4j-core</artifactId>
      <version>[2.16.0,)</version>
      <scope>test</scope>
</dependency>
<dependency>
      <groupId>org.apache.logging.log4j</groupId>
      <artifactId>log4j-api</artifactId>
      <version>[2.16.0,)</version>
      <scope>test</scope>
 </dependency>

You specified [2.16.0,) and this means Maven is fetching last version available from Maven Central.

Artefact log4j-api-3.0.0-beta2 was fetched which requires classes compiled with Java 17 at minimum.

The version has been set to latest 2.x.x and now the tests are working as expected.

@vhyza is it safe to build a package from my local environment and use .zip artefact where needed? In case you don't have time to perform official release.

Hi @rprodan just cruising by, but FWIW I managed to get rid of the test failures also by removing these dependencies for good. It didn't seem to break anything. You can look at my PR for how to build the stuff (using temurin 17 docker image). You should be able to use the zip then. At least I was, until I hit the log4j's security problem, that likely doesn't exist yet at java 8.

Bumped version of ES client dependency to 7.17.20 due to issue with JDK 22 in 7.17.19 (see https://www.elastic.co/guide/en/elasticsearch/reference/7.17/release-notes-7.17.19.html)

@vit-zikmund thank you for your comment. I built the package (elasticsearch-analysis-lemmagen-7.17.20-plugin.zip) myself with maven clean install command

@vhyza if you have time you can easily merge this :)
