Import Saved Search in Detections Rule

[jaredstewart101]

Describe the feature:

Similar to how you can create a visualization in Kibana using a "Saved Search", when you're creating a Custom Rule in Detections you should be able to import query from a "Saved Search".

Describe a specific use case for the feature:

This would be helpful while creating custom rules because right now you have to do the search somewhere else and copy and paste it into the Custom Rule. If you were able to do the search in Discover and save it, you'd be able to import it easier when creating a Custom Rule in Detections.
