Integ Test Refactoring

[vamsi-amazon]

Description

Refactored to skip integ tests with datasources and prometheus in windows platform.

Changes Included:

• Changed release integ tests script to perform datasource creation action only in case of non-windows OS types.
• Changed integ test task to exclude org/opensearch/sql/ppl/PrometheusDataSourceCommandsIT.class
org/opensearch/sql/ppl/ShowDataSourcesCommandIT.class, org/opensearch/sql/ppl/InformationSchemaCommandIT.class in case of non-windows OS Types.
• Fixed Integ Tests failures in windows platform due to line separators.
• Added support for windows in SpawnGradleTask and KillGradleTask. This is required for doctests. Even after fixing this doctests are still failing in windows due to bootstrap.sh. We can tackle doctests fix in a separate issue.

LGTM other than verifying the workflow with github workflow, thanks for the changes!

windows doesn't have a uname or bash, I remember different uname gives different outputs on windows. which uname is this? maybe document prerequisite dependencies in case user wants to run tests on windows

[vamsi-amazon]

This requires Cygwin or MinGW packages and these are installed in the ami used in our build systems. Will mention it as a comment.

CI failed?

[opensearch-trigger-bot]

The backport to main failed:

The process '/usr/bin/git' failed with exit code 1

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-main main
# Navigate to the new working tree
cd .worktrees/backport-main
# Create a new branch
git switch --create backport/backport-1383-to-main
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 8f6793ba63cb8c0301447276ae65a3e3f46563bd
# Push it to GitHub
git push --set-upstream origin backport/backport-1383-to-main
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-main

Then, create a pull request where the base branch is main and the compare/head branch is backport/backport-1383-to-main.
