Automate creation of releases (on github) after every release when the release tag is created

[abhinavGupta16]

Is your feature request related to a problem? Please describe

We manually create the releases (on github) for opensearch and plugins. We want to automate this after a the release once the release tags are created.

Describe the solution you'd like

Add functionality to the release tag job to be able to add releases for opensearch and all the plugins.

Acceptance Criteria

• The releases are created automatically using the release tags job for opensearch, opensearch-dasboards and plugins

I think in order to implement this automation. We will need to standardize our GitHub Releases contents for each release. We will need to decide what we want to include in our Release section. e.g. link or contents of the release notes, download links from opensearch.org for OpenSearch and OpenSearch Dashboards; source codes(.zip & .tar.gz) as assets. I also noticed GitHub action was used to create the Release in some repos on some release version. We could possibly elaborate on that approach.
After we finalize this design part, we could work on this automation across all OpenSearch repos.

@saratvemulapalli will be creating campaigns to track the effort involved in automating the creation of release for OpenSearch 2.2 release.

@saratvemulapalli any update on creating campaigns for this effort?

[saratvemulapalli]

@bbarani looks like it fell through the cracks. I'll take care of this.

We have our first automated github release: https://github.com/opensearch-project/OpenSearch/releases/tag/2.5.0
