Previously, if a DeferredImportSelector was identified at a later stage
as part of processing the collected set of deferred imports, such
selector was processed as a regular import selector.
Semantically, it makes sense as we already are in the deferred phase at
this point and it doesn't make much sense to bother about the extra
contract.
However, Spring Framework 5 introduced the notion of Group that a
deferred import selector can define. When it does, the container has to
honour the contract of the Group rather than calling the simpler
ImportSelector parent contract.
This commit restructures the processing of such case. When a deferred
import selector is detected while processing deferred import selectors,
a group is created with only that selector and the group API is invoked.

Spring Framework 5.1.0 exposed by mistake context in the Kotlin bean DSL
API in order to fix SPR-16269. Now that BeanFactory#getBeanprovider is
available, it should be exposed via a provider<Foo>() function in order
to provide a more clean API instead.

Since non-default constructors are now evaluated for autowiring,
there is no need anymore for setting autowiring mode or exposing
it in Kotlin bean DSL.
Issue: SPR-17292
Support for Kotlin primary constructor and non-default public constructors in addition to default instantiation, aligned with AnnotationConfigApplicationContext and model attribute processing.

Spring 4.3 introduced support for registering a default embedded value
resolver for the default environment, in case of none having been
registered through post-processors (like PropertyPlaceholderConfigurer
and PropertySourcesPlaceholderConfigurer. However, the existing
documentation – stating that a static
PropertySourcesPlaceholderConfigurer bean is required in order for
values coming from @PropertySource declarations to be honored – was not
updated to reflect the change.
This commit addresses this by updating the JavaDoc for @Configuration
and @PropertySource accordingly

This commit introduces a dependency on the Awaitility assertion
framework and makes use of asynchronous assertions in order to make
tests for asynchronous events more robust.
