Adjust configuration support classes so they do not require proxying [DATAMONGO-2226]

[spring-projects-issues]

Christoph Strobl opened DATAMONGO-2226 and commented

We should adjust Abstract*StoreNameHere*Configuration and AbstractReactive*StoreNameHere*Configuration to use @Configuration(proxyBeanMethods=false) to avoid proxying.
Proxying is required when calling instance methods to resolve beans. As alternative, we can use method injection or perform lookups within the config class (e.g. direct usage of ApplicationContext)
