Description

Currently UpdateLog hardcodes the number of logs and records it keeps, and the hardcoded numbers (100 records, 10 logs) can be quite low (esp. the records) in an heavily indexing setup, leading to full recovery even if Solr was just stopped and restarted.

These values should be customizable (even if only present as expert options).
