Move executor from ClusterConfiguration to connection factories as the executor is a Spring concept that isn't tied to endpoint details or the client config.

Reorder static factory methods after constructors and property accessors after static factory methods. Inline single-line single-use methods that aren't intended as extension hooks for easier readability.

Remove NonNull annotations as default non-nullability is defined on the package level.

Simplify tests to use integration tests to avoid excessive mocking.
