(#42) Fix incorrect ceph pool for core2 cluster

The core2 cluster cannot provision pvcs because it's using the k8s-dev
pool when it has credentials valid only for the k8s-prod pool.

This patch adds an entry to the platform cluster map to configure the
pool for each cluster, with a default of k8s-dev.
