Description

Currently the AsyncIndexUpdate is configured within Oak class. This has worked fine so far but now it make certain enhancements difficult.

For example for

• OAK-4935 - To support pre filtering AsyncIndexUpdate needs access to ChangeCollectorProvider
• Enabling Metrics based stats collection requires access to StatisticsProvider
• Config setting - Currently AsyncIndexUpdate makes use of quite a few system properties. It would be better to switch to OSGi based configuration for that

For simplifying such cases we should add a OSGi component which can configure AsyncIndexUpdate

• Support multiple indexers like "async" and "async-fulltext" and also ability to configure the indexing frequency
• OSGi config support

When doing this the component configuring repository must not use withAsyncIndexing
