Adds a configuration option to fact retrievers to define lifecycle for facts the retriever persists. Possible values are either 'items-to-live' or 'time-to-live'. The former will only n number of items in to the database for each fact per entity. The latter will remove all facts that are older than the TTL value.

* { itl: 5 } // Deletes all facts for the retriever/entity pair, apart from the last five
* { ttl: 1209600000 } // (2 weeks) Deletes all facts older than 2 weeks for the retriever/entity pair
* { ttl: { weeks: 2 } } // Deletes all facts older than 2 weeks for the retriever/entity pair
