Description

I see that Classic persistence has the possibility to provide plugin configuration at runtime. But the same feature is missing for typed implementation.

Was there a reason to drop it in the typed version or there is some other technique to handle it?

From Akka's sources, it looks like it is not possible to override it.

One option is to have multiple actor systems in a multi-tenant application, but not sure if this approach is good in general.

Contributor guide

Research direction
Study how Classic persistence allows runtime plugin configuration via `PersistencePluginSettings` and `PersistencePluginSetup`. Then, identify how to expose a similar mechanism in the typed `Persistence.scaladsl` or `javadsl` APIs. Look at the `EventSourcedBehavior` configuration and consider adding a `withSetup` or `configurePlugin` method.
