Previously @ServletComponentScan did not work when there was a
component index on the classpath as it made an assumption about
the concrete type of the BeanDefinitions produced by scanning that
does not hold true when an index is present.

This commit updates the scanning and the handlers to correct the
assumpution by working with a bean definition type that is produced
by scanning both when there is and when there is not an index present.

To prevent the problem from reoccuring, a test that uses and index
has been added and the import of ScannedGenericBeanDefinition is now
prohibited by Checkstyle.

Previously, as soon as the distribution of a release from Artifactory
to Bintray had been initiated we would start checking if it was
complete. This created a race condition between the distribution being
created and us checking if it was complete. If the check won the race
and happened before the creation, Bintray would respond with a 404.

This commit updates BintrayService to wait for up to 5 minutes for the
distribution to be created on Bintray. Once it has been created we
then wait for up to 40 minutes for it to be complete as we did before.

The use of Awaitility has been introduced in this commit to simplify
the logic required to wait for the distribution's creation and
completion.

This commit makes sure that the health endpoint returns a default health
status when no contributors are available. Previously, it was returning
`null` which leads to a 404 when exposed via HTTP.

Prior to this commit constructor bound configuration properties could
not be mocked because it would fail validation from
ConfigurationPropertiesBeanDefinitionValidator. The MockitoPostProcessor
registers the mocked bean as a singleton and validation can be skipped if a
singleton for the type is found in the bean factory.

Fixes gh-18652

This commit fixes a few bugs related to constructor binding.
The ContructorFilter on the Bindable has been replaced with a
Binder level BinderConstructorProvider so that it can be used to
determine the constructor to use for nested properties as well.

Previously, when the configuration properties annotation processor
encountered a property that was the same as an outer type that had
already been processed, it would fail with a stack overflow error.

This commit introduces the use of a stack to track the types that
have been processed. Types that have been seen before are skipped,
thereby preventing a failure from occurring. We do not fail upon
encountering a recursive type to allow metadata generation to
complete. At runtime, the recursive property will not cause a problem
if it is not bound.

Previously, the documentation did not provide any guidance on using
Jersey alongside Spring MVC or any other web framework.

This improves the documentation in two ways:

1. It notes that, in the presence of both Jersey and Spring MVC, the
   Actuator will prefer Spring MVC for exposing HTTP endpoints.
2. It adds a how-to describing how to configure Jersey to forward
   requests for which it has no handler on to the rest of the filter
   chain. When Spring MVC is the other framework, this allows them to
   be handled by its dispatcher servlet.

This commit is a continuation of the work done in 987a5f81. In
addition to developers and licenses that are covered in the earlier
commit, a number of other settings are still inherited from the
starter parent. This commit updates the documentation to show them
being overridden as well.

Previously, @EndpointFilter would only have an effect when used as
an annotation or meta-annotation on the endpoint class itself. It
would have no effect when used on a super-class of the endpoint
bean's class.

This commit updates EndpointDiscoverer so that an @EndpointFilter
annotation or meta-annotation on a super-class will be found and
applied to the discovery process. This is achieved by using find…
rather than get… when retrieving the attributes for the EndpointFilter
annotation.
