Dan Smith 17a8e8a68c Block flavor creation until main database is empty
This makes Flavor.create() fail until the main database has had all
of its flavors migrated. Since we want to avoid any overlap or clashes
in integer ids we need to enforce this. The flavor API was poorly
designed in that it exposes this internal id. Luckily, flavor creation
is infrequent and flavor migration is fast.

The flavors in our database are hard-coded in the first migration,
which means we have to basically do the migration during every
unit test in order to avoid having a legacy environment. Since that
leaves us with deleted flavors in the DB (which screws up the DB
archiving tests), this adds a hard_delete flag to the migration to
do an actual purge of those from our database. What a mess.

OpenStack Nova README
=====================

OpenStack Nova provides a cloud computing fabric controller,
supporting a wide variety of virtualization technologies,
including KVM, Xen, LXC, VMware, and more. In addition to
its native API, it includes compatibility with the commonly
encountered Amazon EC2 and S3 APIs.

OpenStack Nova is distributed under the terms of the Apache
License, Version 2.0. The full terms and conditions of this
license are detailed in the LICENSE file.

Nova primarily consists of a set of Python daemons, though
it requires and integrates with a number of native system
components for databases, messaging and virtualization
capabilities.

To keep updated with new developments in the OpenStack project
follow `@openstack <http://twitter.com/openstack>`_ on Twitter.

To learn how to deploy OpenStack Nova, consult the documentation
available online at:

   http://docs.openstack.org

For information about the different compute (hypervisor) drivers
supported by Nova, read this page on the wiki:

   https://wiki.openstack.org/wiki/HypervisorSupportMatrix

In the unfortunate event that bugs are discovered, they should
be reported to the appropriate bug tracker. If you obtained
the software from a 3rd party operating system vendor, it is
often wise to use their own bug tracker for reporting problems.
In all other cases use the master OpenStack bug tracker,
available at:

   http://bugs.launchpad.net/nova

Developers wishing to work on the OpenStack Nova project should
always base their work on the latest Nova code, available from
the master GIT repository at:

   https://git.openstack.org/cgit/openstack/nova

Developers should also join the discussion on the mailing list,
at:

   http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

Any new code must follow the development guidelines detailed
in the HACKING.rst file, and pass all unit tests. Further
developer focused documentation is available at:

   http://docs.openstack.org/developer/nova/

For information on how to contribute to Nova, please see the
contents of the CONTRIBUTING.rst file.
