DefaultCacheAwareContextLoaderDelegate should log which application context instance was stored or retrieved from cache

[odrotbohm]

The log output in DefaultCacheAwareContextLoaderDelegate.loadContext(…) currently logs details about the cache key used to store or obtain an ApplicationContext instance, but not the object identifier of the context stored or obtained.

If you try to debug a caching issue, it would be helpful if the context identifier was logged as well so that you can find out at what point (or rather: by which test case) the instance retrieved was originally created.

I locally tweaked the log statements to:

logger.debug(String.format("Storing ApplicationContext %s in cache under key [%s]", System.identityHashCode(context), mergedContextConfiguration));

Nice, thanks for the quick turnaround! 👍
