grizzly: keystone apache-style logging format, config has changed

[Tom Fifield]

If https://review.openstack.org/#/c/20738/ is merged, it will introduce a new logging middleware to keystone and introduce a new logging.conf

Taking advantage of this middleware either requires enabling
verbose/debug or utilizing an external logging.conf which configures an
'access' logger.

Example output:

127.0.0.1 - - [2013-01-29T17:15:02.752214] "GET http://localhost:5000/v3/projects HTTP/1.0" 200 16

This patch also revises etc/logging.conf.sample with some more practical
defaults (e.g. supporting externally-managed log rotations) in addition
to illustrating how to generate an 'access.log' file.

See the patch for the new config files
