Ensure ddl-auto=none for non-embedded database

Browse Source 
A more thorough check is needed to avoid the false assumption
that the DataSource is embedded just because an embedded database
is on the classpath. You really have to try and look in the connection
metadata, so that's what we now do.

Fixes gh-621, fixes gh-373

=== Use a custom EntityManagerFactory
To take full control of the configuration of the
`EntityManagerFactory`, you need to add a `@Bean` named
"entityManagerFactory". To avoid eager initialization of JPA
infrastructure Spring Boot autoconfiguration does not switch on its
entity manager based on the presence of a bean of that type. Instead
it has to do it by name.
[[howto-use-traditional-persistence-xml]]
=== Use a traditional persistence.xml
Spring doesn't require the use of XML to configure the JPA provider, and Spring Boot
assumes you want to take advantage of that feature. If you prefer to use `persistence.xml`
then you need to define your own `@Bean` of type `LocalEntityManagerFactoryBean`, and set
the persistence unit name there.
then you need to define your own `@Bean` of type `LocalEntityManagerFactoryBean` (with

Note that Hibernate's own internal property name for this (if you
happen to remember it better) is `hibernate.hbm2ddl.auto`. You can set
it, along with other Hibernate native properties, using
`spring.jpa.properties.*` (the prefix is stripped before adding them
to the entity manager). Also relevant:
`spring.jpa.generate-ddl=false` switches off all DDL generation.
