Failed to deploy so artifacts in nexus

Failed to deploy so artifacts in nexus

More problems encountered since mso repos were renamed.

We now have found that this declaration in the top-level so pom
causes the deploy to fail with a 403 Forbidden error:

        <groupId>org.openecomp</groupId>
        <artifactId>so</artifactId>

We are changing this to:

        <groupId>org.openecomp.so</groupId>
        <artifactId>framework</artifactId>
