Stanislaw Pitucha 2c1524866a Improve external lock implementation 
Remove a number of limitations from the external locks.
- They can be nested now
- They do not need external cleanup in case of failures
- They do not rely on lockfile or greenlet internal implementation

New implementation is based on fcntl locks and any crashing process
will drop the lock. It does not have to rely on any cleanup code or
handling exceptions. Because no cleanup is needed, a number of tests
have been removed.
This implementation is not portable outside of POSIX/BSD/SVR4 systems.

Fcntl locks should work correctly with NFS mounts.

Locks are cleaned up after the tests finish running via run_tests.sh,
even though it's not strictly needed.

This change requires eventlet >= 0.9.17.

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 on Twitter.

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

http://docs.openstack.org

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:

http://github.com/openstack/nova

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

https://lists.launchpad.net/openstack/

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://nova.openstack.org/

Changes to OpenStack Nova should be submitted for review via the Gerrit tool, following the workflow documented at:
