Description

It's possible to improve /batch/events.json endpoint of the event server performance by using batch inserting in storage implementations. For example, Elasticsearch has bulk API and also JDBC has batch updating.

I propose adding LEvent.futureInsertBatch() that takes Seq[Event] and modify /batch/events.json endpoint to use it. The default implementation is calling existing futureInsert() per event, and we can override it in the storage implementation to use storage specific batch inserting API.
