@zeeklop took a look at #19354 (comment) and it seemed like the path of least resistance was to just add a nullable remediation_steps to the event context. Let me know if y'all see any issues with this and if not I'll go ahead and move forward with this approach.

Thank you @ryan-carroll-graylog I'm taking a look now. Should I add the front-end changes to this branch?

No problem @zeeklop, yeah I think adding everything to this branch makes sense while we work out the details. I don't think it'll be a big changeset.
