[WLM] add wlm support for scroll API

[kaushalmahi12]

Description

This change mitigates the warn level logs from QueryGroupTask#getQueryGroupId method when the queryGroupId is null. Currently all APIs which use SearchTask or SearchShardTask for task level resource tracking have to call the setQueryGroupId method otherwise this results in generating the log mentioned in the related issues.

@kaushalmahi12 Are we missing tests that could have caught this issue?

[kaushalmahi12]

@andrross I think it would a good idea to add a test which will cover all the APIs. Let me do that next.

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-2.x
# Create a new branch
git switch --create backport/backport-16981-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 c5ab16264d5e3624e2cf368f475ff3b5bc6e0bf9
# Push it to GitHub
git push --set-upstream origin backport/backport-16981-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-16981-to-2.x.
