[FR][DAC] Consideration: Support Bulk Actions

related to #3407

---

**This is a consideration and not a commitment to work at this point**. We should review the feasibility and supportability. If it is doable and not deemed maintainable, we can move the example code to the DAC reference for users to manually implement.

- The current `actions.py` schemas need to be looked at closer to confirm that they accurately match what kibana expects and known limitations. (e.g. `throttle`)
- We need to develop a decision tree to determine the precedence (should actions defined in rules or actions defined in the toml be authoritative)
- We need to bundle the actions.toml files when exporting / importing
