Fixing integration test starting

[asalamon74]

Description

When I want to run the integration tests with ./gradlew check I've got an error message:

> Could not resolve all files for configuration ':qa:kerberos:downloadHadoop#3.3.2'.
   > Could not resolve hadoop.common:hadoop-3.3.2:hadoop-3.3.2.

and the test are not started.

Issues Resolved

The error message is a bit misleading, we are trying to download artifacts from https://apache.osuosl.org/ but the required versions are not available anymore. After updating the version numbers I've got new errors:

> Could not resolve opensearch-distribution-snapshot:opensearch:2.13.0-SNAPSHOT.
         > Could not get resource 'https://artifacts.opensearch.org/snapshots/core/opensearch/2.13.0-SNAPSHOT/opensearch-min-2.13.0-SNAPSHOT-linux-x64-latest.tar.gz'.
            > Could not HEAD 'https://artifacts.opensearch.org/snapshots/core/opensearch/2.13.0-SNAPSHOT/opensearch-min-2.13.0-SNAPSHOT-linux-x64-latest.tar.gz'.
               > The server may not support the client's requested TLS protocol versions: (TLSv1.2, TLSv1.3). You may need to configure the client to allow other protocols to be used.

                  > Received fatal alert: handshake_failure

I can fix this with a gradle.properties change.

The next error message is keytab releated

 What went wrong:
A problem was found with the configuration of task ':qa:kerberos:hadoopFixture#namenode.configure' (type 'DefaultTestClustersTask').
  - In plugin 'org.opensearch.gradle.JdkDownloadPlugin' type 'org.opensearch.gradle.testclusters.DefaultTestClustersTask' property 'clusters.integTest$0.nodes.$0.extraConfigFiles.opensearch.keytab$0.file' specifies file '/home/systest/opensearch-hadoop/qa/kerberos/build/fixtures/kdcFixture/opensearch.keytab' which doesn't exist.

We need to create keytabs at the beginning. I've also fixed this.

Finally I've got the following error message:

Caused by: org.opensearch.hadoop.rest.OpenSearchHadoopRemoteException: no handler found for uri [/_security/user/client] and method [POST]
        at org.opensearch.hadoop.rest.ErrorExtractor.extractError(ErrorExtractor.java:108)
        at org.opensearch.hadoop.rest.RestClient.checkResponse(RestClient.java:473)
        ... 7 more

I'm not too familiar with this API but I have the feeling that this is some ancient code from elasticsearch and opensearch have a different API.

Can someone with opensearch experience help here?

-Was it possible to run these tests ever? Some of my fixes indicates that it's not working for a long time.
-Is it worth committing this half-solution? At least we can start the tests and some of them are working with this.
-I think it would be better to fix this no handler for uri error. Can someone help me what is the correct API here?
