    METRON-827: Fix full dev build dependency multi-threading issue with maven

    I was experiencing issues spinning up full dev 2x in a row. The observed behavior was
for me to see old code deployed in RPMs the first run, and no RPMs in the build output or
in /localrepo on the VM during the second run. I believe this may have been a race condition
introduced when we added `-T 2C` for multi-threading the build to the "build metron artifacts"
Ansible task. Since the projects had no explicit dependency, the ordering may not have been
consistent from run to run and machine to machine. To address this, I've added pom dependencies
for the metron-deployment project on metron-platform and metron-analytics.
    Test by spinning up full-dev.
