Looking forward to this getting merged soon :)

index-management depends on alerting plugin, and the alpha-1 version update (issue #1373) cannot be done in ism until it is completed in alerting plugin.

Hi @AWSHurneyt are we able to fix and merge this PR to unblock others?

Thanks!

[AWSHurneyt]

The failing tests are either security-enabled tests (as mentioned in opensearch-project/notifications#1002 (comment), the security-enabled test workflow needs to be refactored away from using docker), or backwards compatibility tests (example).

Will take a follow-up item to refactor those workflows, and get this bump PR merged to unblock bumping security analytics.

Thanks @AWSHurneyt , I approve this PR on the base that code assemble is passing.
So we can unblock other plugins that depends on alerting.

Thanks.
