Adding Github action for auto backport PR creation

[VachaShah]

Signed-off-by: Vacha [email protected]

Description

This Github action creates backport PR automatically when appropriate labels are added to the PR on main. Once the original PR gets merged to main, this Github action will open backport PR. For example, if we want to backport a PR to 1.x, add label backport 1.x to the original PR, once this PR is merged, the Github action will open a backport to 1.x PR from the original PR.

Reference: https://github.com/marketplace/actions/backporting
I tried this on my own repo and was able to create appropriate backport PRs. Example: VachaShah/TestGithubActions#7

I think it's worth adding a "backports" section to https://github.com/opensearch-project/OpenSearch/blob/main/DEVELOPER_GUIDE.md as well.

Once we are happy with this, let's run a campaign for 1.3 to add this to all plugins/components?

@VachaShah Feel free to merge! Want to create some backport labels, especially for 1.x branch, too?

Thanks @dblock ! I added the details in the DEVELOPER_GUIDE.md for auto backports. Will create backport labels as well.

Hi @dblock , looks like I don't have permissions to create labels on the repo.

@VachaShah

1. Did you resolve the labels problem?
2. Should we run a campaign in 1.3 to use this workflow for all plugins? If yes, start by creating a parent issue in https://github.com/opensearch-project/opensearch-plugins/issues similar to Default CI Java Version to Java 11, run tests on 8, 11, 14 (and attempt 17) opensearch-plugins#64 and link it from campaigns in [RELEASE] Release version 1.3.0 opensearch-build#889

I believe this would help all the repositories in the opensearch-project.
Instead of https://github.com/opensearch-project/opensearch-plugins, can we create an issue and document it in https://github.com/opensearch-project/.github?

That would be in https://github.com/opensearch-project/project-meta maybe? Either way, I want to make sure we can track that campaign for plugins as part of an OpenSearch release, separately, as well.

@dblock, yes the OpenSearch label was created and I will do the same for other repos. I will create the parent issue shortly for other repos and track one for plugins as well.
