INT-4365: Improve notPropagatedHeaders function

Browse Source 
JIRA: https://jira.spring.io/browse/INT-4365

It is much useful to configure the `notPropagatedHeaders` as a set of
patterns to match.
In this case we can filter a group of headers with the common prefix or
suffix

* Allow to configure `AbstractMessageProducingHandler.setNotPropagatedHeaders`
as simple patterns; the `*` means filter all - not copy request headers
at all - similar to `transformer` behavior
* Add `ConsumerEndpointSpec.notPropagatedHeaders()` for Java DSL
* Add `not-propagated-headers` to the `<service-activator>`

Address PR comments; some other improvements

* Fix `ConsumerEndpointSpec#notPropagatedHeaders()` log message
* Improve `AbstractMessageProducingHandler.notPropagatedHeaders() logic
so any `*` in the set of patterns eliminates all others since it has
a highest priority
* Expose `requires-reply` for the `<transformer>` as a `true` by default
* Refactor a bit `AbstractStandardMessageHandlerFactoryBean` hierarchy to
avoid duplicated code

* Fix `message.adoc`
* Add `noHeadersPropagation` flag to the `AbstractMessageProducingHandler`
* Rework logic in the `updateNotPropagatedHeaders()` to store the array
of patterns instead of `Set` to avoid extra operation on each message
* Combine `noHeadersPropagation` with the `shouldCopyRequestHeaders()`
in the `createOutputMessage()` for logic to determine if we should start
the copy-headers procedure at all

* Revert `AbstractMessageProducingHandler.selectiveHeaderPropagation`
* Optimize `AmqpOutboundGatewayParserTests` performance from 3 secs to 0.5

Fix more NPEs in the `AbstractMessageProducingHandler`

Starting with _version 4.3.10_, you can configure message handlers (that modify messages and produce output) to suppress the propagation of specific headers.
Call the `setNotPropagatedHeaders()` or `addNotPropagatedHeaders()` methods on the `MessageProducingMessageHandler` abstract class, to configure the header(s) you don't want to be copied.
You can also globally suppress propagation of specific message headers by setting the `readOnlyHeaders` property in `META-INF/spring.integration.properties` to a comma-delimited list of headers.
IMPORTANT: Header propagation suppression does not apply to those endpoints that don't modify the message, e.g. <<bridge, bridges>> and <<router, routers>>
Starting with _version 5.0_, the `setNotPropagatedHeaders()` implementation on the `AbstractMessageProducingHandler` applies the simple patterns (`xxx*`, `*xxx`, `*xxx*` or `xxx*yyy`) to allow filtering headers with a common suffix or prefix.
See `PatternMatchUtils` JavaDocs for more information.
When one of the patterns is `*` (asterisk), no headers are propagated; all other patterns are ignored.
In this case the Service Activator behaves the same way as Transformer and any required headers must be supplied in the `Message` returned from the service method.
The option `notPropagatedHeaders()` is available in the `ConsumerEndpointSpec` for Java DSL, as well as for XML configuration of the `<service-activator>` component as a `not-propagated-headers` attribute.
IMPORTANT: Header propagation suppression does not apply to those endpoints that don't modify the message, e.g. <<bridge, bridges>> and <<router, routers>>.
