Description
Extend org.apache.lucene.monitor.MonitorConfiguration with an ability to configure how cache purge task is scheduled by org.apache.lucene.monitor.Monitor (aka Luwak). In particular allow to use an external ScheduledExecutor.
Currently each new instance of org.apache.lucene.monitor.Monitor is creating a new thread in order to schedule a periodic cache purge task. This is fine as long as your application is using a small number of Monitor instances but if for some reason you want to create a large number of Monitor instances (e.g. to separate different business domains) you end up with excessive number of threads created.
