FATAL: all hosts have already failed -- aborting

Glance is trying to create an endpoint when Keystone is not completely setup.

    Reduce dependencies on the dest nodes

    Currently we require a slew of deps on each destination node, this
    includes a gcc compiler and installing things via pip. We can remove
    these dependencies by containerizing them and running and Ansible
    inside the container itself. The container would then report back
    facts about idempotency.
