> Fix flaky OpensearchIndexIT - disk usage exceeded flood-stage watermark

> Key: CAMEL-24018
> URL: https://issues.apache.org/jira/browse/CAMEL-24018
> Project: Camel
> Issue Type: Bug
> Components: camel-opensearch
> Reporter: Guillaume Nodet
> Assignee: Guillaume Nodet
> Priority: Major
>
> The {{OpensearchIndexIT}} integration test is flaky on CI. Over the last 12
> days, it shows 7 failed runs and 7 flaky runs out of 215 total runs.
> All 5 test methods in the class fail with the same root cause:
> {code}
> cluster_block_exception: index [twitter] blocked by:
> [TOO_MANY_REQUESTS/12/disk usage exceeded flood-stage watermark, index has
> read-only-allow-delete block]
> {code}
> This happens because the OpenSearch test container disk fills up on CI
> machines with limited disk space. When disk usage exceeds the flood-stage
> watermark, OpenSearch puts all indices into read-only-allow-delete mode,
> causing all write operations to fail with 429 Too Many Requests.
> The fix has two parts:
> # Disable disk allocation watermarks in the OpenSearch test container
> configuration so the container never blocks writes due to disk pressure.
> # Add {{@AfterEach}} cleanup in {{OpensearchIndexIT}} to delete the "twitter"
> index after each test, preventing data accumulation across tests.
