This patch uses cfg.CONF as ConfigOpts in common/config instead of creating a new instance of it. This is needed since most of Oslo's modules use the global CONF object to register their config parameters. The patch also moves log.setup call into Bootstrap and calls it after configs are loaded. Fixes bug: #1190524 Change-Id: Ib601418a7dbcad84c79b640b93bc5798ec4a62c4
