The etcd data store is leftover in the <install dir>/.clusterapi_output/etcd dir when infrastructure provisioning fails. This takes up a lot of local storage space and is useless.

    Always

    1. Start an install
    2. introduce an infra provisioning failure -- I did this by editing the 02_infra-cluster.yaml manifest to point to a non existent region
    3. Check .clusterapi_output dir for etcd dir
    

    etcd data store remains

    etcd data store should be deleted during infra provisioning failures. It should only be persisted to disk if there is a failure/interrupt in between infrastructure provisioning and bootstrap destroy, in which case it can be used in conjunction with the wait-for and destroy bootstrap commands.
