Register a oslo.messaging entry point in the oslo.config.opts namespace
which, when called, returns a list of the configuration options which
may be registered by the library at runtime.
The idea here is that the sample config file generator can query this
and include the returned options in the sample config file of any
applications which use the library.
Some sample code for fetching available options:
import pkg_resources
for ep in pkg_resources.iter_entry_points('oslo.config.opts'):
if ep.name == "oslo.messaging":
list_opts = ep.load()
for g, opts in list_opts():
opts.sort(key=lambda x: x.name)
print "[%s]" % g
for o in opts:
print "%s = %s" % (o.name, o.default)
print

The set_time_override function in timeutils was written as a
helper function to mock utcnow for unittests before 'mock' was
generally used. Now that we have mock and fixture, we no longer
need to use it.

Partial-Bug: #1266962
* Get the current line at runtime, don't hardcode the line number
* Only strip last character of the filename if it ends with ".pyc"
or ".pyo". On Python 3, import automatically replaces .pyc and
.pyo with .py.
* Use threading.current_thread().ident to get the identifier of the
current thread. The get_ident() function is available in thread
module in Python 2, but in threading module in Python 3. And on
Python 3, logging.thread symbol does not exist anymore.

basestring does not exist anymore in Python 3: use six.string_types instead.
In "try: .../except Exception as err: ...", err is a local variable, it does no
more exist after the except block. Copy the exception in a new cls_error
variable to fix Python 3 support.
Extract of Python 3 documentation: "When an exception has been assigned using
as target, it is cleared at the end of the except clause. (...) Exceptions are
cleared because with the traceback attached to them, they form a reference
cycle with the stack frame, keeping all locals in that frame alive until the
next garbage collection occurs."

Manually applied ef406a21782134aeefb944f74b3f1a47d6169318 from
oslo-incubator to get the fix required for bug 1257293.
Copying the original commit message from oslo-incubator below.
"""
When multiple RPC servers (consumers) are subscribed to the same RPC
topic, a single RPC request to that topic should be received by only
one of the consumers. A bug in the QPID driver caused every consumer
to receive a copy of the RPC request. This bug affects only Topology
version 2. This patch will cause a single queue to be created for
each topic, and shared among all consumers of that topic. This
results in each RPC request being received by only one consumer,
in turn across all the competing consumers.

We need to support deprecated transport driver configurations like:
rpc_backend = nova.rpc.impl_kombu
i.e. 'nova.rpc.impl_kombu' is a deprecated alias for 'rabbit'.
Initially, we supported this by adding the aliases to each project's
setup.cfg:
oslo.messaging.drivers =
nova.rpc.impl_kombu = oslo.messaging._drivers.impl_rabbit:RabbitDriver
However, this means that code like this:
url = str(TransportURL(conf))
generates a bogus URL string like:
nova.rpc.impl_kombu://...
We need to apply these transport aliases when we load drivers, but also
when we create transport URLs from configuration containing potentially
deprecated aliases.
To enable that, add an aliases parameter to TransportURL(),
TransportURL.parse() and get_transport().
