Previously, the ehcache statistics were computed on the activity of the
last minute which gives a "live" overview. All others cache managers,
including JCache, provides a "cumulative" metrics (i.e. the hit/miss
ratio since the creation of the cache or the last time it got cleared).

Ths commit aligns the ehcache statistics to provide a similar semantics
as the other cache managers. The side effect is that the metrics are now
available, even if there is no cache activity at all at the moment.

Assert using epoch time

Add TimeZone in date assertion

This commit updates `GitInfo` to use a proper `java.util.Date` rather
than a raw String. Because the Maven and Gradle plugin do not agree on a
format, `ProjectInfoAutoConfiguration` now registers a `Converter` that
is taking care of translating the raw `String` to a `Date`.

See gh-2484

This commit updates "simple" configuration classes to use constructor
injection. Simple means that there are no optional dependencies
(@Autowired(required=false) is not used), and none of the dependencies
use generics.

Configuration classes that are not simple will be updated in a second
pass once https://jira.spring.io/browse/SPR-14015 has been fixed.

  Info endpoint

`InfoProvider` is now `InfoContributor` and contributes to the `Info`
instance via a builder. The `Info` instance is immutable. Each
contributor can be disabled via the `management.info.<name>.enabled`
key or all can be disabled using `management.info.defaults.enabled` (this
is similar to what the health endpoint does).

By default, all keys from the environment starting with `info.` are
exposed. If a `git.properties` file is present in the classpath, the
content of `GitInfo` is exposed using the `git` key.

A `SimpleInfoContributor` and `AbstractEnvironmentInfoContributor` are
available for convenience. `InfoContributor` instances can be ordered
the usual way, with a default order provided by
`InfoProviderAutoConfiguration#DEFAULT_ORDER`.

This commit moves `GitInfo` to a general "project info" area that will be

Previously, only dependency management for logback-classic was
provided. This meant that it was possible for logback-core, upon
which logback-classic depends, to have a different version.

This commit adds dependency management for logback-core, thereby
ensuring that the two dependencies will have the same version.

Closes gh-5304

Shutdown handling has been improved so that it will run after any
EntityManagerFactory beans have been closed. This ensures that Hibernate
can, if configured to do so, drop its schema during restart processing.
Without this change, a benign exception could be logged if the database
was shutdown before Hibernate.

This commit introduces a new failure analyser for
NoUniqueBeanDefinitionException. The analyser provides details of the
consumer whose dependency could not be satisfied and the names and
sources of the non-unique beans.

This analysis requires access to the BeanFactory, so FailureAnalyzers
has been updated to support BeanFactory injection via an analyzer
implementing BeanFactoryAware.

This reverts 2ecb33f7 and largely reverts 2c619f8d.

docker-java 3.0 was causing a variety of problems and it appears that
we can get things working with Docker Java 2.2.x and Jackson 2.6.

This commit allows to generate the packaged artifact only locally by
adding a new `attach` property. If `attach` is set to `false` explicitly,
only the main artifact is installed/deployed.

Previously, the launch script integration tests ran happily on OS X and
on Bamboo’s Linux instances. With the upgrade to docker-java 3.0 that
is no longer the case with the default DockerClientConfig failing on
Bamboo as the default DOCKER_CERT_PATH location does not exist.

This commit updates the client configuration so that it attempts to
build the configuration once in it default configuration and, if this
fails, it tries again without TLS verification. This skips the check
of DOCKER_CERT_PATH’s validity.

If a `MessageConverter` bean is available, we now associate it to the
created `RabbitTemplate` and `RabbitListenerContainerFactory`. That way,
registering a custom `MessageConverter` is all that's needed.

The Rabbit auto-configuration is now using the new `ObjectProvider` that
offers a nicer API to detect if a primary candidate is available for
optional collaborators.
