feat(workflow_engine): Add support for Issue Status Changes

[saponifi3d]

Description

Whenever an Issue Group has a new activity, an Activity model is created.

This PR adds a registry to when an activity is created, so we can have a hook into when the model is created.

This also adds a handler for the registry, workflow_issue_status_change. This method will take the Activity, and create a WorkflowEventData object.

All of the conditions marked as WORKFLOW_TRIGGERS can work with Activity | GroupEvent already.

The ACTION_FILTER conditions were updated accordingly, most are just saying they don't know how to be evaluated for now.

Let me know if it'd help to break this PR up for review -- i have a few branches that built up this PR.
