In response to the cessation of per-commit tarballs produced by the CI
systems, simplify the version processing code. We did many many many
complicated things to support producing release artifacts that were not
actually supported release artifacts. After a bunch of issues emerged, it was
determined that the best way forward was to stop producing quasi-not-really
non-release tarballs. If people want to consume versions of openstack that
are not released versions, the git repos are always available.
Additionally, this patch removes versioninfo and just uses PKG-INFO and
pkg_resources to handle version processing.

This reverts commit 525ac47.
There are already two ways to reference an option in a group:
CONF.group.key
CONF[group].key
Adding a third variant doesn't seem ideal. Also, for the specific case
of LazyPluggable in Nova, we can easily just pass an optional config
group name to the constructor.

This currently fails for client projects as python_package
is the name of the project, while package is where versioninfo
is written to. This doesn't affect server openstack projects
because python_package == package.
This hasn't affected any client projects yet because most likely
none of them call version.canonical_version_string() in their
setup.py

default arguments were being set to a
list instead of a dict. This caused
problems if the args key was missing
in the msg argument to the call/cast methods.
Adds tests to check if RPC cast/call work
without arguments. Changes and documents
the _test_cast method arguments, allowing
for more flexibility and code reuse.

Let us check if the opt_name has a '.', if it does then split it
into a group/key and try lookup using that combination. Since
LazyPluggable uses "CONF[self.__pivot]" if we just add this
capability to cfg, we get "LazyPluggable doesn't support
option groups" for free.

When the rpc message envelope patch went in, the serialization done in
impl_zmq was replaced with what is done in rpc.common. Instead, it just
needs to be done as an additional stage of serialization. The reason is
that the amqp drivers can handle passing dicts into the messaging
libraries. The zeromq library can not handle that, so it has to ensure
it is a string before passing it down to the library.
This patch restores the original (unmodified) _serialize() and
_deserialize() methods in impl_zmq that were removed and calls them as
appropriate.

When message envelopes were added for rpc messages, notifications were
explicitly left out. This was due to the fact that notifications are
consumed outside of OpenStack. However, notification consumers will
likely want to eventually start taking advantage of some of the features
that the envelope is a prerequisite for, such as message signing.
This patch adds a new notification driver that produces message based
notifications including the message envelope.

On the consumer side, each message is consumed in a separate thread
but we currently have no way of waiting for all these threads to
complete.
In BaseRpcTestCase.test_call_timeout(), we complete the thread while
there is still a message handler running on the other side. This can
mean the consumer attempting to send its reply while other tests
are running, which clearly is a bad thing.
Make the connection close() and reset() methods in the kombu and qpid
drivers wait on proxy object threads before returning to avoid this
situation.

checks to is_older_than and is_newer_than functions against str instead
of basestring.

a target right now and there's no "standard" way to support it right now
in openstack.

This patch adds a message envelope that includes a envelope format
version number. This message envelope will allow us to embed
additional metadata later on, such as a signature for the message
payload.
Up to this point, we've deferred message serialization as a
responsibility of the messaging library we're using by passing it a
message as Python types and letting it deal with how to pass it over a
network. This patch adds json serialization in the rpc layer of the
application message payload before passing the message down into the
messaging library.
There are some benefits to be gained by doing a pass at serialization
ourselves. As an example, we occasionally hit serialization bugs that
only affect some messaging drivers. The kombu driver has always had a
nice advantage. It uses anyjson internally for serializing messages,
which we hook into using our jsonutils module. When there is a problem
serializing, we automatically use to_primitive() to fix it. This patch
allows all drivers to take advantage of this automatic message fix-up.
This also creates a convenient common hook point for messages coming in
and out of the system, regardless of the driver in use.
While this changes the base format of the messages sent between nodes,
it has been done in a backwards compatible manner. The new message
format will not be used by default. The idea is that all nodes will be
upgraded to a version that is capable of receiving the new format
(Grizzly) before switching it on. We will turn it on post-Grizzly.
Implement blueprint version-rpc-messages.

Copies current nova-rootwrap code to openstack.common, so that it
can be reused by Cinder and Quantum.
Implements blueprint common-rootwrap.
Before it can be used in projects, update.py needs to grow the
capability to deploy files in bin/ and etc/, as well as replacing
a placeholder text by the destination project name in source files
and binary names.
In this proposed version, the placeholder text is "oslo".

Need to get rid of the deferred string approach as
the problem was overriding string methods is hard and
flaky. There is just no other documented
argparse hook to allow deferring of the version
calculation as version passed in has to be a str
or buffer. Added a test to try longer string and even
run it in a loop just to be sure.

Before this fix which was included in eventlet 0.10.0:
https://bitbucket.org/which_linden/eventlet/issue/92/eventletgreen-override-of-oswaitpid
the os.wait() wrapper in eventlet would not block if no child processes
had exited. This was clearly buggy behaviour and os.wait() no blocks
correctly. However, it appears it now does not return if the parent process
was interrupted by a signal. This means that you can't kill the parent process
and have the child processes cleaned up gracefully.
To avoid all these issues, switch to non-blocking wait behaviour. We use
WNOHANG with waitpid() to poll for an exited child process and, if there
is none, we yield to other green threads and sleep for a short period.
This means excessive CPU usage, though, which will be tracked by
bug #1095346.
Check pid to avoid some unnecessary warning/info messages in the logs
