Upgrade Notes for Dropwizard 0.7.x

• Update Java source and target versions in maven-compiler-plugin to 1.7 (most applications should be already on 1.7);
• Replace Maven dependencies from com.yammer.dropwizard to io.dropwizard;
• Replace package statements from com.yammer.dropwizard to io.dropwizard throughout the codebase;
• If you use dropwizard-db, update configuration class to use DataSourceFactory;
• If you use dropwizard-hibernate, update Hibernate bundle by overriding getDataSourceFactory;
• If you use dropwizard-migrations, update Migrations bundle by overriding getDataSourceFactory;
• If you serve static files, add dropwizard-assets to dependencies;
• If you use templating, add dropwizard-views-freemarker or dropwizard-views-mustache accordingly;
• Update the application to override getName() instead of providing the bundle with the name;
• Change how resources are added from environment.addResource(resource) to environment.jersey().register(resource);
• Once everything is compiling, rename *Service class to *Application;
• Change test classes extending ResourceTest to use ResourceTestRule;
• Convert app.yml to the new server layout (see ServerFactory and ConnectorFactory);
