Update to use released parent poms

Update ccsdk/oran to use released version of parent poms in preparation
for release build.  This is needed because ccsdk-oran Jenkins job is
set up to use maven version plugin to roll version, instead of simply
removing all occurrences of '-SNAPSHOT' in pom.xmls before doing staging
build.  Jenkins job should be changed not to use version plugin so that
in the future we don't have to change parent pom version before release
build.
