Polish "Support default headers with RestTemplateBuilder"

Broaden the scope of customizer support so that instead of focusing
just on headers, we can now customize any outgoing `HttpClientRequest`.
Also update auto-configuration to automatically add any
`RestTemplateRequestCustomizer` beans to the builder.
