Currently feature collection in mjolnir runs a multi-search for each feature individually. Now that the ltr plugin is (or soon will be) available in prod and relforge it would be good to switch this over to collecting features from the ltr query as well.

I started to work on feature logging from the plugin, I think I'll continue on the plugin and use it in mjolnir.
Problem right now is that I can only obtain the explain output from a model, it means that a dummy model must be created before the fact. Logging inside the plugin should work with feature set and exisiting models.
So because both options (logging in the plugin vs explain) require some work in the plugin:
- implement logging
- extend sltr query to accept a featureset
I prefer to go with the long term approach and implement proper feature logging (unless there's some urgency in doing otherwise)?
