Prior to this commit, the `ResourceHttpMessageConverter` would support
converting from an `HttpInputMessage` to a `InputStreamResource`. This
is valid when reading resources on the server side, but it's not
compatible with the way `RestTemplate` works.
The API exposed by `RestOperations` imply that the HTTP server response
should be fully consumed and properly closed by the time the `exchange`
method returns. In other words, this HTTP client does not support
streaming the HTTP response.
This commit allows the `ResourceHttpMessageConverter` to be configured
to disable read streaming when used in `RestTemplate`.

Prior to this commit, the `ResourceRegionHttpMessageConverter` would
rely on the default implementation of `getDefaultContentType` to guess
the default Content-Type of the resource region to be written to the
HTTP response. That implementation fetches the first media type
provided in the HTTP request "Accept" header.
This behavior is not correct when converting resources and this commits
aligns this converter with the `ResourceHttpMessageConverter` which uses
JAF to guess the correct Content-Type of the given resource, or just
returns "application/octet-stream" as a default value.

The most common use case is specifying JSON views.
ServerResponse.BodyBuilder#hint(String, Object) allows to
specify response body serialization hints.
ServerRequest#body(BodyExtractor, Map) allows to specify
request body extraction hints.

An update on the last commit switching from:
List<Locale> getAcceptLanguageAsLocales() to
Locale getAcceptLanguageAsLocale()
This best supports the scenario for the most preferred Locale.
If there is a need to look at the prioritized list of languages it's
best to use Locale.filter with the LocaleRange's.
This is explained in the Javadoc for getAcceptLanguage().
Issue: SPR-15024
The use of Locale.LanguageRange for the Accept-Language header makes
sense as it gives the most flexibility for a client to set a weighted
list and for a server to do filtering via Locale#filter.
This commit adds an additional convenience method that turns
the LangugeRange list to a list of Locale's also filtering out a
wildcard (i.e. "*"). A List<Locale> is the most basic way to access
prefered languages and needed when filtering is not required.

Previously ForwrdedHeaderFilter did not ensure that
HttpServletResponse.sendRedirect worked properly based on
X-Forwarded-* headers.
This commit updates ForwardedHeaderFilter to overrided the
HttpServletResponse.sendRedirect method to ensure
X-Forwarded-* headers are honored.
Issue SPR-15020
ServerWebExchange.Builder has an additional Consumer-style shortcut
method that accepts a builder for modifying the request.
ServerWebExchange and ServerHttpRequest builders have fewer methods,
more use-case focused vs matching directly to properties.
ServerWebExchange now provides access to "requestParams" as a
MulitValueMap with query parameters and form data combined.
The combined map is then used for the params condition of
@RequestMapping purposes () and also for @RequestParam arguments.
Issue: SPR-15000
This is similar to the WriteListener changes on the ServerHttpResponse
where we are more naturally exposed to a delayed write. Nevertheless
we could also have a delayed read and should be consistent. The early
initialization of the RequestBodyPublisher also simplifies the
internal implementation a bit.
Instead of registering an AsyncListener in ServletHttpHandlerAdapter
we now register an AsyncListener in each of the request and response
where the events need to be handled anyway. This allows removing the
package private delegation methods in the request and response.
