Final set of changes to remove the diffs carried to make UFO work with
OpenStack Swift. The code is now a complete layering on top of OpenStack Swift
where we either "monkey patch" or subclass as necessary.
See BZ 870589 (https://bugzilla.redhat.com/show_bug.cgi?id=870589).
There are a lot of changes here due for the most part to rearranging the
directory hierarchy to have create a proper python module hierarchy under the
"gluster" namespace. Plugin references have been removed. The differences that
used to be in the swift.diff file are now replaced with server implementations
for account, container, object, and proxy that subclass the swift versions.
Additionally, the plugins/conf directory has been moved to the "etc"
directory, and the plugins/bin directory promoted a level.
Unit tests pass.
A new setup.py file is provided so that the install process can use it for
creating all the necessary python install infrastructure (eggs and paste
support).
A new RPM spec file is provided which to properly install the new code, and
the sample configuration files have been modified to reference the new python
egg.

Refactor code to use the devices configuration file setting for account,
container, and object servers, dropping mount_path from the fs.conf file, and
constructing new account, container and object server rings.
This removes the next to last set of diffs in the swift diff file. See BZ
870589 (https://bugzilla.redhat.com/show_bug.cgi?id=870589).
The key to the change is the dropping of the pre-built account, container and
object rings, instead providing a script that will generate them for the user
given the gluster volume name in use. In addition, we override the Swift
check_mount() method and replace it with Gluster's which attempts to
"auto-mount" if it is not already mounted.
The following is an enumeration of the changes contained in this refactoring:
* The refactoring to override the Swift check_mount() involved condensing
a lot of code, removing redundancies and simplifying methods across a
number of modules
* Drop checking the mount point in the low level DiskDir, DiskAccount and
DiskFile objects now that Swift's normal mount checking is used, and
enable it by default in the template configuration file
* Add missing get_container_timestamp() method for DiskAccount objects
* Fix the plugin RPM spec file to provide the new ring builders, and while
we were at it, finally fix the over-writing of the configuration files
on install
* Bug fixes
* The monkey patched version of check_object_creation was not working
correctly due to a missing import of HTTPBadRequest and a bad
reference to validate_obj_name_component()
* Only have the utils module import the plugins constraints module for
the side effect of monkey patching if gluster is enabled
* Removed the db_file.db file in the tree since it is created on the
fly
* Updated 2011 copyright notices to 2012

The upstream Swift code base contains the following commit which adds the
ability to modify constraint values using the swift.conf file:
https://github.com/openstack/swift/commit/a2ac5efaa64f57fbbe059066c6c4636dfd0715c2
These changes rely on the above commit being back-ported to Swift 1.4.8 (see
https://github.com/portante/swift/commit/fc2421b04022ac6bbe9d5014362ec5f99f94c5e0).
As a result, a good number of differences we carry can be removed, since the
provided swift.conf file now contains the values we need.
Along with these changes, we add middleware to get constraints loaded properly
(via monkey patching) until subclassing is implemented in a future commit. We
further simplify the diffs to a minimal set by storing the timestamp in file
system metadata and moving new files to the plugins/middleware directory.
Note that the original "gluster" middleware was in the swift.diff file, and
has been renamed to "glusterfs" and moved to the new plugins/middleware
directory. The "gluster" middleware is now a temporary way to get the
constraints properly loaded (both of these middleware pieces should disappear
in future commits when we refactor further to subclass the Swift objects
instead of patching them).

Ahead of further refactoring to make things a bit easier to review, we have
restored some of the code formatting as it was in the original constraints.py
file from which this file as copied.
