[refactor][broker] Use AuthenticationParameters for rest producer

[michaeljmarshall]

Motivation

In #19975, we introduced a wrapper for all authentication parameters. This PR adds that wrapper to the Rest Producer.

Modifications

• Use AuthenticationParameters to simplify parameter management in Rest Producer.
• Add method to the AuthorizationService that takes the AuthenticationParameters.
• Update annotations on Rest Producer to indicate that a 401 is an expected response.

As discussed on the mailing list https://lists.apache.org/thread/w4jzk27qhtosgsz7l9bmhf1t7o9mxjhp, there is no plan to release 2.9.6, so I am going to remove the release/2.9.6 label
