SM-2274: Upgrade to Camel 2.13.0

- Upgraded the Camel version in pom
- Altered CXF examples features to load cxf-core instead cxf (since cxf is not amongst the boot features and will load spring)
- Moved CXF examples itests to separate containers due to logging interceptor registration problems (I assume this is because of the new camel shutdown policy)
