KieServices.Factory.get().getKieClasspathContainer() doesn't discover KieModules in a non-Maven project

If you try to use a ClassPath Container KieContainerImpl uses a ClasspathKieProject that scans the classpath for pom.xml or pom.properties files. If the consuming project is not a Maven project (and hence lacks either a pom.xml or pom.properties file) no KBases/KSessions defined in the consuming project's kmodule.xml and /resources folder are discovered.

This also manifests as a problem when running Maven WebApp projects in IDEA (other IDE's and project types may be similarly affected). IDEA copies the JARs sources and resources to the target folder at runtime; which excludes the module's pom.xml and pom.properties files.

Consequentially ClasspathKieProject fails to determine a ReleaseId for any KieModules defined in the module and hence fails to discover any KBases/KSessions too.

This is defined in https://github.com/ederign/uf-social-activities/blob/master/uberfire-social-activities/uberfire-social-activities-backend/src/main/resources/META-INF/kmodule.xml

Rules being in https://github.com/ederign/uf-social-activities/tree/master/uberfire-social-activities/uberfire-social-activities-backend/src/main/resources/org/uberfire/social/activities/drools-rules

Workaround is to include a dummy pom.properties; as we did here https://github.com/ederign/uf-social-activities/blob/master/uberfire-social-activities/uberfire-social-activities-backend/src/main/resources/META-INF/maven/pom.properties
