Upgrade to Hibernate 5.1, whilst still retaining compatibility with
Hibernate 4.3. This commit introduces the following changes:
* Add SpringPhysicalNamingStrategy to provides lowercase/underscore
table names support. This should be equivalent to the previous
SpringNamingStrategy that was used with Hibernate 4. No
ImplicitNamingStrategy is provided since the Hibernate 5 defaults
appear to be roughly equivalent to the conventions used in Spring
Boot 1.3
spring.jpa.hibernate.naming.
* Migrate `spring.jpa.hibernate.naming-strategy` to
`spring.jpa.hibernate.naming.strategy` and provide additional
properties for physical and implicit.
* Add `spring.jpa.hibernate.use-new-id-generator-mappings` property and
default to `false` when on Hibernate 5 to retain back compatibility.
