I only just moved logging from nova to common, so behavior should remain the same.

Implements blueprint multi-process-api-service
This is based on Huang Zhiteng's patch.
This patch adds support for running services as multiple processes. This
is primarily intended to be used with the API service as a way to provide
more concurrency than eventlet can sometimes provide.
A SIGTERM or SIGINT signal will cause the parent process to gracefully
terminate the child processes, allowing them to finish processing the
requests currently being processed. The parent will wait for the
children to finish before exiting.

Add multiprocess support for API serivces (EC2/OSAPI_Compute/OSAPI_Volume/Metadata).
2012-06-1 v7:
* Add unittest to cover worker recovery, service termination functionality
in wsgi.py, fix python 2.6 compatibility issue.
* Modify generate_uid() to introduce per-process seeds in utils.py to avoid
collisions.
* Add worker session to nova.conf.sample.
2012-05-21 v6:
* Fix 'test_wsgi' unittest error.
2012-04-28 v5:
* Add SIGINT handler and fix child-parent race condition when Ctrl+C is
pressed.
2012-03-31 v4:
* Fixed typo, removed debug code.
2012-03-30 v3:
* Fixed localization/pep8 error in unittest, add metadata test.
* nova/wsgi.py:Server: use the greenthread pool created for each process.
* nova/service.py: remove debug code
2012-03-27 v2:
* Fixed unittest error.
* nova/wsgi.py:Server: Use self._logger to do logging in multiprocess mode.
* nova/wsgi.py:Server: Move self._pool creation into proper place.
* code style fix.
2012-03-25 v1:
* Modification to nova/service.py and nova/wsgi.py in order to support
multiprocess (a.k.a. workers) for various API services. If multiprocess
mode is enabled, (i.e. flags 'APINAME_workers' set to positive numbers),
corresponding API service will run in target number of process(es). There
is also a master_worker process spawned for managing all workers (handling
signal/termination).
* Add unittest for multiprocess API service, also alter testing/runner.py
to adopt new unittest.

Implements blueprint cfg-global-object
Replace nova.flags.FLAGS with openstack.common.cfg.CONF.
In future, we can do a s/FLAGS/CONF/ across the codebase.
