Spring Data JDBC has deprecated its INSTANCE constants in its MariaDB
and MySQL dialects as the required configuration for the dialect
varies depending on the configuration of the DB.
This commit adapts to this deprecation by changing Boot's
DataJdbcDatabaseDialect to resolve the underlying dialect through a
DB query for its MARIA and MYSQL values.

This commit adds a spring-boot-persistence module with data technology
independent features. This provides a better home for EntityScan and
PersistenceExceptionTranslationAutoConfiguration.
