Unlike Java 8, 9, and 10, Java 11 does not tolerate a null URL being
used to create a URLClassLoader. The Atmosphere sample looks for
a resource named /WEB-INF/classes which only exists in a packaged
war application. In all other cases the resulting URL is null.
Atmosphere uses this to create a URLClassLoader which fails on Java
11.
This commit updates the sample to customize the handlers path. There
are other web application-specific assumptions in Atmosphere, such as
the scanning of WEB-INF/lib by default. This change appears to get
the sample going, but we should, perhaps, consider removing it in the
longer term, particularly as Boot itself has no Atmosphere
integration.

- Modifying dependencies to starter-web with tomcat exclusion plus
alternative servlet container instead of manual dependency on
spring-webmvc as it is the preferrable way to use alternative servlet
container
- Previously RestTemplate with ssl was configured manually in tests - now
it rellies on autoconfiguration - changed this for multi-connector test
and added test to ensure that ssl autoconfiguration is working
- Most samples with alterntative servlet containers used some kind of
service reading property and returning default since it wasn't
configured - removed it, since it is not specific to using alternative
servlet containers.
