Adjust AbstractJdbcConfiguration so it does not require proxying [DATAJDBC-339]

[spring-projects-issues]

Mark Paluch opened DATAJDBC-339 and commented

We should adjust  to AbstractJdbcConfiguration 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)
