GH-3169: DSFL: addSessionFactory based on Object

Browse Source 
Fixes https://github.com/spring-projects/spring-integration/issues/3169

All other `DefaultSessionFactoryLocator` contracts are based on the `Object`,
so this `addSessionFactor`y has to be on `Object` as well.

* Add `DefaultSessionFactoryLocator.addSessionFactory(Object key, SessionFactory<F> factory)`
* Deprecate existing one based on `String`
* Fix tests do no use a deprecated API
* Some other code style clean up in the affected classes

**Cherry-pick to 5.2.x**
