Extract the targetNamespace from the WSDL, generate the SEI and WebServiceClient annotated classes´ package names from it & write it together with the project´s package name into a cxf-spring-boot-maven.properties to enable Complete automation of Endpoint initialization

[Jonas Hecht]

To enable the Complete Automation of Endpoint Initialization in the cxf-spring-boot-starter (Issue here), we need the package name of the SEI implementing class to properly scan for. The securest way is to extract the groupId from the pom while executing this plugin and providing it into a cxf-spring-boot-maven.properties in the classpath.
