This commit updates ConfigurationPropertiesScanRegistrar to apply the
same component scan filters than the ones applied on standard classpath
scanning.

As a result, configuration properties scanning is automatically disabled
in slice tests and can be included by an explicit import or a dedicated
TypeFilter implementation if necessary.

  Fix formatting in Couchbase smoke tests

Closes gh-17519

Remove `runner` since we're no longer tied to JUnit 4.

See gh-17491

Meta-annotate `ClassPathExclusions` and `ClassPathOverrides` with
so that the `ModifiedClassPathExtension` no longer needs to be
used directly.

See gh-17491

Remove the `ModifiedClassPathClassLoaderFactory` in favor of
factory methods on `ModifiedClassPathClassLoader`.

Replace any direct `junit-platform-launcher` dependencies and instead
rely on the test runner providing it. Launcher related class are not
handled via reflection.

This update allows us to workaround SUREFIRE-1679.

Closes gh-17517

Delete our internal `OutputCaptureRule` since we not longer have any
tests using it.

  Polish ModifiedClassPath support
  Migrate ModifiedClassPath tests to JUnit 5
  Add JUnit 5 ModifiedClassPathExtension
  Extract ModifiedClassPathClass logic
  Migrate to MockRestServiceServer
  Polish LoggingApplicationListenerTests

Delete `ModifiedClassPathRunner` since we no longer have any tests
that use it.

Migrate the remaining JUnit 4 tests to JUnit 5, making use of the
new `ModifiedClassPathExtension`.

See gh-17491

Add a JUnit 5 extension that allows tests to be run with a
modified classpath. Since JUnit 5 does not currently offer a way
to run tests with a different classpath, we instead fake the
original invocation and launch an entirely new run for each
method.

See gh-17491

Extract classes from `ModifiedClassPathRunner` so that they can
be reused.

See gh-17491

Migrate `RestClientTestWithoutJacksonIntegrationTests` to use
Spring's `MockRestServiceServer`.

Migrate a new tests to use the `ApplicationContextRunner`.

Merge some string lines that were previously split because of the
90 chars wide formatting.

Update `OutputCaptureRule` so that it now implements
`CapturedOutput` and can be used directly with AssertJ.

Align with the recent upstream Spring Framework changes triggered by
their issue #23170.

Closes gh-17492

Setting the log file name to a random value in smoke tests
doesn't work because the logger context has already been initialized.

Closes gh-17486

Using a random value for the logfile name caused
the logfile endpoint to return a 404 as the name
was resolved from the environment on every request.
This commit registers a bean for LogFile which is then
used by the logfile endpoint.
