This commit adds support for reactive library types to be returned
directly from controller methods adapting them either to a
ResponseBodyEmitter (streaming) or DeferredResult (non-streaming).
The reactive libraries supported are the ones that can adapted to a
Reactive Streams Publisher through the ReactiveAdapterRegistry.

StringDecoder can be created in text-only vs "*/*" mode which in turn
allows a more intuitive order of client side decoders, e.g. SSE does
not have to be ahead of StringDecoder.
The commit also explicitly disables String from the supported types in
Jackson2Decoder leaving it to the StringDecoder in "*/*" mode which
comes after. This does not change the current arrangement since the
the StringDecoder ahead having "*/*" picks up JSON content just the
same.
From a broader perspective this change allows any decoder to deal with
String if it wants to after examining the content type be it the SSE
or another, custom decoder. For Jackson there is very little value in
decoding to String which works only if the output contains a single
JSON string but will fail to parse anything else (JSON object/array)
while StringDecoder in "*/*" mode will not fail.

CharSequenceEncoder now supports all MIME types, however since encoding
Flux<String> can overlap with other encoders (e.g. SSE) there are now
two ways to create a CharSequenceEncoder -- with support for text/plain
only or with support for any MIME type.
In WebFlux configuration we insert one CharSequenceEncoder for
text/plain (as we have so far) and a second instance with support for
any MIME type at the very end.

Support for flushing in EncoderHttpMessageWriter is now driven from a
configurable list of "streaming" media types with the list including
"application/stream+json" by default.
As a result Jackson2ServerHttpMessageWriter is no longer needed.
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.
This commit adds an overloaded DataBufferUtils.read method that operates
on a AsynchronousFileChannel (as opposed to a ReadableByteChannel, which
already existed). This commit also uses said method in the Resource
encoders, if the Resource is a file.
This commit *adds* the "intercepted" headers to the ClientHttpRequest,
as opposed to replacing them, which is what happened before this commit.

Prior to this commit, the org.springframework.tests.Assume class could
fail to load resulting in a NoClassDefFoundError if parsing of the
'testGroups' system property failed. This is because the parsing took
place while initializing a static field.
This commit addresses this issue by moving the 'testGroups' system
property lookup to a dedicated method that is lazily invoked upon
demand instead of eagerly when loading the Assume class itself.
In addition, when an error occurs, TestGroup.parse() now logs the
complete original value of the supplied test groups string instead of
potentially omitting the "all-" prefix. This results in more
informative error messages similar to the following.
java.lang.IllegalStateException: Failed to parse 'testGroups' system
property: Unable to find test group 'bogus' when parsing testGroups
value: 'all-bogus'. Available groups include:
[LONG_RUNNING,PERFORMANCE,JMXMP,CI]
