The `spring.metrics.export.redis.aggregate-key-pattern` is no longer
defined but was still referenced in the documentation.

The `strategy` group is not detected in the meta-data because the
Strategy inner class is not defined at the "right" level in the
hierarchy.

For now, `@NestedConfigurationProperty` was added to workaround the
issue. Once gh-3454 is solved, we should remove them.

Fix `CacheManagerValidatorPostProcessor` that could lead to early bean
initialization.

Fixes gh-3440

Add documentation for server.session.cookie keys

See gh-3240

Add `spring.resources.static-locations` to the reference documentation
appendix.

Fixes gh-3372

Add ApplicationArguments interface which allows SpringApplication.run
arguments to be injected into any bean. The interface provides access
to both the raw String[] arguments and also provides some convenience
methods to access the parsed 'option' and 'non-option' arguments.

A new ApplicationRunner interface has also been added which is
similar to the existing CommandLineRunner.

Fixes gh-1990

Provide additional space between the ConfigFileApplicationListener order
and the LoggingApplicationListener order.

Fixes gh-2543

Add support for the following server properties which can be used to
configure the session:

	server.session.tracking-modes
	server.session.cookie.name
	server.session.cookie.domain
	server.session.cookie.path
	server.session.cookie.comment
	server.session.cookie.http-only
	server.session.cookie.secure
	server.session.cookie.max-age

In addition `server.session-timeout` is now deprecated and has been
replaced with `server.session.timeout`.

Fixes gh-3240

When using Tomcat, Azure automatically configures an environment
variable called LOGGING_CONFIG that configures the
java.util.logging.config.file system property.
LoggingApplicationListener finds this configuration via the Spring
environment (it looks for logging.config) and attempts to use it as the
name of the logging configuration file. Since c3d93f70 this failure
causes the app to fail to start, rather than the previous behaviour of
silently falling back to the default configuration.

This commit updates LoggingApplicationListener to only consider
configuration that is a non-empty string and that does not start with
-Djava.util.logging.config.file=, which is the beginning of the default
configuration on Azure, and is very unlikely to be part of the name of a
logging configuration file.

Unfortunately, we have no other choice to flip the ignoreUnknownFields
attribute of `SecurityProperties` has many different target are now set
for that namespace outside the class. See gh-3445 for a potential way
to improve that.

Closes gh-3327

This might just be me but when I read the original javadoc it made me
think that caching worked only if the endpoint is accessed anonymously.

Update DataSourceHealthIndicator to support pattern based matching for
DB2 products. Prior to this commit product identifiers of the form
`DB2/LINUXX8664` were not supported.

* pr/3435:
  Add flyway and liquibase endpoint documentation
  Add 'flyway' and 'liquibase' actuator endpoints
  Add serialization endpoint tests

See gh-3434

Add `/flyway` and `/liquibase` actuator endpoints to provide details of
any database migrations that have been applied.

Fixes gh-3434
Closes gh-3435

Test basic serialization in Endpoint tests to ensure that JSON
can always be produced.

Ensure that FlywayAutoConfiguration and LiquibaseAutoConfiguration occur
after HibernateJpaAutoConfiguration so that the DependsOnPostProcessor
condition can correctly check for a LocalContainerEntityManagerFactory
bean.

Fixes gh-3437

This reverts commit 8f16ebd0.

Replace @ConditionalOnExpression usage in auto-configuration in favor
of faster direct Environment access.

Replace the previously used `EndpointWebMvcConfiguration`
`spring.factories` key with a dedicated ManagementContextConfiguration
annotation.

Also renamed the EndpointWebMvcHypermediaConfiguration and
EndpointWebMvcConfiguration classes to make it clearer that they are
for the management context.

See gh-3345

Update the `ManagementServerPort` detection logic to attempt direct
property resolution before looking for a local property bean
definition. Bean definitions provided by auto-configuration classes
are ignored.

This change allow `OnManagementMvcCondition` to use the
`ManagementServerPort` to determine when `EndpointWebMvcConfiguration`
should apply (removing the need to create a temporary context).

See gh-3345

Refactor `EndpointPathRequestMatcher` so that the side effect of setting
`endpointHandlerMapping` in the parent class is a little more obvious.

Not sure why it's there but it's far too broad.
