We might want to turn on/off converting and merging per datasource instead of turning them on/off globally, and having a whitelist for datasources. (i.e. whitelist for each function...?)

Not critical though since initially we will be well served by setting convert segments on, merge off, and not having a whitelist. But one day, when we migrate a low volume batch pipeline to the indexing service, we may want to enable merging for that pipeline but not for others that have not yet been migrated.

Or whatever, since we can just hold off on all merging until everything is migrated.
