Add procedures to split indexing, search and merge

[VijayanB]

Description

For large dataset, users might prefer to do indexing, search, force merge as different test execution. To support this use case, added three additional procedure,
1)index only, 2)force-merge 3)search-only. This can be used in nightly to run search workload every day without indexing everytime.

Integration test is executed here: https://github.com/VijayanB/opensearch-benchmark/actions/runs/8256914251

Please add information on these new test procedures in the README. If this workload is to be backported to the 1, 2 and 3 branches, please add the corresponding backport labels.

Can you also indicate in the description that you have run the integ tests as indicated here? This is needed for approval -- thanks.

Also, you may want to move the different phases each into a separate file in the test procedures directory and include them in the appropriate test procedures to avoid code duplication. For instance, the force-merge section could be shared amongst both the no-train-test and force-merge procedures.

@gkamat Thanks for feedback. I updated procedure with your suggestion. Can you take a look one more time? Thanks

As mentioned in my prior comment, please indicate in the PR description that you have run the OpenSearch Benchmark integration tests prior to merging this change. Although this is a different repository, the tests can fail if there are issues with the workload. Also indicate which versions of OpenSearch this workload is targeting.

@gkamat It should work on 1.x 2.x and main . Will update with it results

@gkamat i followed the steps and shared the execution result. However i am not sure how the test will pickup main branch from workloads.

The test will not pick up the main (i.e., the development) branch. It only uses branches 1 and 2 since those are the only versions of OpenSearch currently available.

The backport to 2 failed:

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

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-2 2
# Navigate to the new working tree
pushd ../.worktrees/backport-2
# Create a new branch
git switch --create backport/backport-230-to-2
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 ee086332fe6f73d87f0cb90d67ed77db5359f807
# Push it to GitHub
git push --set-upstream origin backport/backport-230-to-2
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2

Then, create a pull request where the base branch is 2 and the compare/head branch is backport/backport-230-to-2.
