Build log_handler documentation

When log_handler.py was added to oslo.messaging changes weren't made to
publish the documentation. This patch ensures the docs for log_handler
are built.

Remove vim header

We don't need vim modelines in each source file, it can be set in
user's vimrc.

Closes-Bug: #1229324
Use driver's notify_send() method again

Drivers have a notify_send() method which allows for special semantics
to be implemented for notification sending. During the port over to
oslo.messaging, it appears we stopped using this and switched to just
using topic_send() instead.

Lets restore the use of notify_send() so that we don't lose behaviours
like I9f8dfd6eaf3996be58fecff6ad91508bdcef23f3 added.

Add kombu driver library to requirements.txt

The RabbitMQ driver is the default driver for oslo.messaging, so it
makes some sense to require this by default. This is consistent with
the way e.g. Nova has always required kombu.

Clean up for qpid tests

Use the config object in the base class, and define a local
base class for managing connections instead of repeating
that code in several places.

Fixed possible pep8 failure due to pyflakes bug

There is a bug in pyflakes that may trigger F811 violation when import
is not used in a file before its redefinition in local class method
scope, even though it's used in other classes later in the same file.

Use messaging_conf fixture configuration by default

This simplifies usage of messaging_conf fixture, reduces explicit
cleanup and option registration code in unit tests.

Fixed inconsistent EventletContextManagerSpawnTest failures

The test spawns a greenthread and expects it to complete after
eventlet.sleep(0) call. The problem is that if there are other
greenthreads currently running, sleep(0) may switch to unexpected
thread, which may result in test thread not being invoked at all.
Instead of assuming no other green threads are running at the moment
of test execution, explicitly wait() for the test thread.
