Blocker Description
The release instructions at https://cwiki.apache.org/confluence/display/WHIRR/How+To+Release use the legacy Maven repos. We should follow the new process described in http://www.apache.org/dev/publishing-maven-artifacts.html. To do this requires getting Whirr set up on Nexus (I opened INFRA-2969 for this), and then modifying the top-level POM and release instructions to support the standard process.
