This commit makes changes to WebClient and WebTestClient in oder to
limit setting the body according to HTTP method and also to facilitate
providing the request body as Object.
Specifically, this commit:
- Moves methods that operate on the request body to a RequestBodySpec
in both WebClient and WebTestClient, and rename them to `body`.
These methods now just *set* the body, without performing
an exchange (which now requires an explicit exchange call).
- Parameterizes UriSpec in both WebClient and WebTestClient, so that
it returns either a RequestHeadersSpec or a RequestBodySpec.
Issue: SPR-15394
This commit deprecates `AsyncRestTemplate` and related types
(`AsyncClientHttpRequestFactory` etc.) in favor of the Spring 5.0
`WebClient`.

This commit folds ServerHttpMessage[Reader|Writer] into its parent
HttpMessage[Reader|Writer] with the server methods pre-implemented
by default to be simple pass-through delegates.
This commit changes the `MediaTypeFactory` to return
`Optional<MediaType>` (instead of a plain `MediaType`) for the
`getMediaType` methods.
Issue: SPR-14908
This commit changes the `MockServletContext.getMimeType` method to use
`MediaTypeFactory` instead of JAF. It also adds a `addMimeType(String,
MediaType)` method to customize the mime types returned from said
method.

ExchangeMutatorWebFilter now supports multiple mutator registrations
for the same request header id by creating a single composed function.
Issue: SPR-15250
This commit adds a common base class for server-less setup with the
option to configure a transformation function on the
ServerWebExchange for every request.
The transformation is applied through a WebFilter. As a result the
RouterFunction setup is now invoked behind a DispatcherHandler with
a HandlerMapping + HandlerAdapter.

Currently the BOM versions are:
* reactor-core 3.0.6.BUILD-SNAPSHOT
* reactor-netty 0.6.2.BUILD-SNAPSHOT
This commit fixes as well a few deprecations in reactor-core.
The WebTestClient API no longer provides access to a base
ExchangeResult without a decoded response body.
Instead the response has to be decoded first and tests can then
access the EntityExchangeResult and FluxExchangeResult sub-types.
The WiretapConnector now decorated the ClientHttpRequest & Response
in order to intercept and save the actual content written and read.
The saved content is now incorporated in the diagnostic output but may
be used for other purposes as well (e.g. REST Docs).
Diagnostic information about an exchange has also been refactored
similar to command line output from curl.
Clearly separate how the result of an exchange is represented before
the response body has been read (e.g. assertions on status and headers
only) vs later after the body is extracted to a representation
(assertions on the extracted body) or is decoded to Flux<T> (e.g. for
use with a StepVerifier).
WebTestClient now defines all the steps from setup to performing
an exchange and applying expectations.
The order of expectations now ensures the response status and headers
are verified first since that's available before the body is consumed
and also because it determines how the body is to be decoded, i.e.
error vs success scenarios.
There is now a built-in option for verifying the response as a Map
along with Map-specific assertions.
There are similar options for verifying the response as a List as well
as whether to "collect" the list or "take" the first N elements from
the response stream.
Rather than returning ExchangeActions that contains ExchangeInfo and
applies a chain of assertions, the exchange operation in WebTestClient
now has an extra step to decode the response.
The outcome of that is ExchangeResult<T>, parameterized with the
decoded body type, and containing the request and response details,
also providing access to built-inassertions via an assertThat()
instance method.
This approach lends itself better to decoding and asserting response
body types with generecis. It is also more friendly to using any
assertion library such as AssertJ since you get the result first
and then deal with assertions.
