The ConnectionFactory can be used early in user configuration to
configure an `Exchange`. Such connection may not hold the proper
MetricCollector and can be cached, leading to missed metrics
information.
This commit moves the configuration of RabbitMQ metrics to a
BeanPostProcessor so that the proper MetricCollector is configured
before any connection is created.

Previously, when the Jersey-based Actuator was configure with a
separate management port, the resulting child context would fail to
start due to their being no ResourceConfigCustomizer beans available.
This commit updates the configuration so that the customizer's are
injected using an ObjectProvider and an empty list is used in the
event of their being no customizer beans. This aligns the child
context configuration class with JerseyAutoConfiguration which
already used this approach.
Closes gh-12975
Update `MeterRegistryConfigurer` to also apply customizers to
composite meter registries. Prior to this commit composites were
skipped due to the incorrect assumption that did not contain
their own state.

Previously, when performing lazy initialisation of the context,
ApplicationContextRequestMatcher assigned the context field before it
called initialized. The context being non-null is used as the signal
that it’s ok to call a subclass’s matches method. If one thread checks
for a non-null context in between the field being assigned and
initialized being called on another thread, matches will be called
before the subclass is ready.
This commit closes the window for the race condition by only assigning
the context field once the subclass’s initialized method has been
called.
There is a secondary problem in each of the subclasses. Due to the use
of double-checked locking in ApplicationContextRequestMatcher, it’s
possible for a subclass’s matches method to be called by a thread that
has not synchronised on the context lock that’s held when initialized
is called and the delegate field is assigned. This means that the
value assigned to the field may not be visible to that thread.
This commit declares the delegate field of each
ApplicationContextRequestMatcher subclass as volatile to ensure that,
following initialisation, its value is guaranteed to be visible to
all threads.

Spring Integration no longer requires a `MicrometerMetricsFactory` to
support Micrometer metrics so there's nothing for Boot to
auto-configure.
See gh-12287
Update `EndpointRequest` to that the `PathMappedEndpoints` bean is
optional. A missing bean is treated as if there are no path mapped
endpoints.
Fixes gh-12238
Update `ApplicationContextRequestMatcher` and
`ApplicationContextServerWebExchangeMatcher` to use a supplier for
the context, rather than the context itself.
This allow exceptions to be propagated to subclasses which may choose
to deal with them.
See gh-12238
Update `spring-boot-actuator-autoconfigure` so that it no longer has
a dependency on `spring-boot-test-autoconfigure`. This will allow us to
add test support for actuator concerns in the future if we need to.
Fixed gh-12270
This commit changes invocations to immediately return the expression
instead of assigning it to a temporary variable. The method name should
be sufficient for callers to know exactly what will be returned.
Closes gh-12211
Update the configurable embedded web server factory interfaces to
extend `ConfigurableWebServerFactory` so that the can be used in a
`WebServerFactoryCustomizer`.
Extract server specific customization to their own auto-configuration
and align reactive/servlet server auto-configuration.
Closes gh-8573
This commits move the Hikari metrics registration to a BeanPostProcessor
as the Hikari datasource cannot be modified once its configuration has
been sealed (usually happens when `getConnection` is invoked on the
pool).
