    Removing archaic references

    This document was originally imported from Nova. Removing some of the
    old references to Quickstart and Hypervisors.

    http://docs.openstack.org/developer/cinder/devref/development.environment.html
    has a dangling link to a ../quickstart document (removed long ago.)
