Fix JmsProperties bean not found exception

Update JndiConnectionFactoryAutoConfiguration to ensure that the
JmsProperties bean is created. Prior to this commit deployment to
a WildFly would fail with a NoSuchBeanDefinitionException.

Fixes gh-2072
Detect SpringBootServletInitializer @Configuration

Update SpringBootServletInitializer to automatically add itself as a
SpringApplication source if it is annotated with @Configuration.

Also throw a more meaningful exception if no sources have been
configured.

Fixes gh-2073
Add deployment integration tests

Add deployment tests for Tomcat, TomEE and WildFly to ensure that
a basic Spring Boot application can be deployed to a traditional
Application server.

Since the deployment tests can be quite slow, they currently only
run in the "full" build profile.
