Fixing DockerFile to avoid IOException

chown on /opt isn't enough as files/directory permissions needs change so that onap user can access to execute
Even if chown onap:onap was done, it was failing to create/run script due to permission issues

Adding noCache to docker-maven-plugin so that it won't pick cached layers
