Initial Version to Monitor Github workflows using the automation app

[prudhvigodithi]

Description

Initial Version to Monitor Github workflows:

• Onboard workflow to capture the pull_request.closed and workflow_run.completed events.
• Onboard the github-merged-pulls-monitor and github-workflow-runs-monitor to parse the events and index to the metrics cluster.
• Add utility class OpensearchClient to use AwsSigv4Signer and connect to the metrics cluster.
• Update the OperationConfig to support the new configSchema for args.
• Added the missing license header for the code files and added .licenserc.json.
• Tests for OpensearchClient and github-merged-pulls-monitor and github-workflow-runs-monitor.
• Updated the build.yml to build-test.yml to include some testing during the PR creation.

I think all of this needs tests at a minimum. There's no way we're going to have an app where thousands of lines of code gets deployed across all repos without some assurance that they will actually work.

I agree with you @dblock, I'm waiting for Peter to define a test workflow in this repo, we should add tests and proper code coverage before we switch to public.
Thanks

Yes DB, I totally agree we need test here.
Once we get it public tomorrow we will start adding tests to it before adding more functions.

Thanks.

Added few tests for OpensearchClient in test/utility/opensearchclient.test.ts, @peterzhuamazon please let me know if we want to have testing done this way or any specific framework to be used for this automation app.
Thank you
