Add DataSourceConfig setName() and build() method to build DataSourcePool

Then the DataSourcePool can be created via build() rather than using
the DataSourceFactory explicitly like:

    DataSourcePool pool = new DataSourceConfig()
     .setName("test")
     .setUrl("jdbc:h2:mem:tests")
     .setUsername("sa")
     .setPassword("")
     .build();
