Corrected logic for validating taskId against ContainerId with UserTaskAdminService API.  Created additional test cases. (#936)

Adding testcase for UserTaskAdminService which verifies correct lookup of container by its alias. (#935)

JBPM-5914:  UserTaskAdminService API doesn't display correct error when using bad container ID (#931)

Moving exceptions to API module so that it is exported and accessible to GWT/Errai

JBPM-5897 - Fails to start a process with CorrelationKey which is unique but includes correlation properties of an existing correlation key (#926)

Creates a new project (analogy to drools/drools-test-coverage and jbpm/jbpm-test-coverage)
in droolsjbpm-integration repository.

The new project will contain more QE tests, starting with additional integration tests
of kie-maven-plugin model classes instrumentation.

Artificial dependencies on kie-maven-plugin and kjar-with-instrumentation-wrapper
have been added to make sure that the required project are built before the projects that
depend on them, even during Maven parallel build (-T).

This reverts commit 6812647e.

The build is failing as there are build order issues between the kie-maven-plugin
and the introduced test-suite module. This needs to be fixed and then
committed again.

This is needed to make sure that KIE Server is not sending away the
marshalled inernal hibernate types (like e.g. PersistentBag). Those
then can not be un-marshalled unless hibernate is on classpath.
This was an issue in workench where the hibernate was recently removed
from WEB-INF/lib.
