so/libs build fails if unit tests are disabled

[ERROR] Failed to execute goal on project nova-client: Could not
resolve dependencies for project org.openecomp.so.libs.openstack-
java-sdk:nova-client:jar:1.2.0-SNAPSHOT: Could not find artifact
org.openecomp.so.libs.openstack-java-sdk:openstack-client:jar:
tests:1.2.0-SNAPSHOT

I've also noticed that the junit and mock artifacts are not
consistently declared with scope "test".

Will fix these issues, and clean up indentation in the poms.
