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.
