KIP-1145 — Kafka Streams `CloseOptions` should not have a public constructor

Discussion Streams

Proposes making the `CloseOptions` class in Kafka Streams not directly instantiable via a public constructor, replacing it with a builder or factory pattern. A public constructor on `CloseOptions` prevents the API from evolving (adding fields with defaults) without breaking binary compatibility, since any caller constructing it directly would break if the constructor signature changes.
