Clone index input in multipart upload flow

[sachinpkale]

Description

• In multipart upload flow, we open IndexInput for each part and this can cause exhaustion of virtual memory for the OpenSearch process.
• In this PR, instead of creating new IndexInput instance, we clone the original IndexInput instance. Cloned IndexInput instance makes sure not to create a separate map entry in the virtual memory.

Test failures seems flaky. Re-triggered the build.

❕ Gradle check result for c4cf7f4: UNSTABLE

Please review all flaky tests that succeeded after retry and create an issue if one does not already exist to track the flaky failure.

good to add a debug/trace log line for places where the close is happening to check in future if any potential leak happens.

Overall, looks good and should fix the virtual memory issue that we have seen.
