This commit introduces a @DynamicPropertySource annotation that can be
used on methods in test classes that want to add properties to the
Environment with a dynamically supplied value.
This new feature can be used in conjunction with Testcontainers and
other frameworks that manage resources outside the lifecycle of a
test's ApplicationContext.
Closes gh-24540
