Add splunk queries for predictions and missing events.

@e0d 

The "no peer assessments" query is essentially a template for various events that are important to us. TBD if we want to actually create different alerts based on every event type. Or if we just want to pick a couple of them knowing that we'd catch the anomolies anyway.

The other query is the predictive query and I haven't worked in an alert on it yet, but wanted you to take a look.
