Allow file logging config

* Fixes lp904305
* remove module level log functions (getLogger to rule them all)
* Move specific Environment logging to the one place it is used
* Wrap getLogger to return a logger wrapped in a NovaContextAdapter
* Do not overwrite the root logger
* save_and_reraise_exception logs via error for passing exc_info
* Uses CommonConfigOptions for compatability across Openstack Projects
* Prefers CommonConfigOptions over legacy options
* Install a NullHandler on the root logger if configured by FLAGS
* Include example logging config file to mimic Nova defaults
