This documentation moves the specific `build-image` execution
configuration example of the Maven plugin documentation to the general
plugin configuration. This makes sure that it works in most cases and
an execution-specific configuration is not required here anyway.

With the introduction of Gradle we lost the list of version properties
that were previously in the spring-boot-dependencies POM and were also
linked inside the documentation. This commit introduces an appendix
section in the docs and links the appropriate places to the new section
to restore discoverability.

This commit hard codes the default value so that the annotation
processor picks it up. The default value is tested for consistency so
this is acceptable as providing the default value in the metadata
requires to hard code it anyway.

refresh can only ever be called with a ConfigurableApplicationContext
and we want to evolve the refresh API to reflect that. This commit
takes the first step by overloading refresh(ApplicationContext) with
a new refresh(ConfigurationApplicationContext) method and deprecating
refresh(ApplicationContext). Where the call to refresh is made, the
argument is cast to ApplicationContext to ensure that
refresh(ApplicationContext) is called. This ensures that any existing
override of the method is still effective.
