Batch event insertion

The eventlogging database consumer generates single-row inserts.
From a performance perspective (master overhead and slave replication lag)
it would be better to batch inserts to the same table. Batches do not
need to be large or of a particular size.

Events get grouped per schema and batched every 10 seconds.
Still missing some more tests for new functionality.
