shade and openstacksdk each have a logging doc and a logging setup helper
function. They both basically do the same thing, and we have a TODO item
about collapsing them.
This moves openstack.utils.enable_logging to openstack.enable_logging
(leaving behind a compat piece at openstack.utils.enable_logging) It
adds the shade functionality to it, and also changes the behavior to
match shade's WRT behavior when no parameters are passed (defaults to
logging to stdout)
Update the codebase to call openstack._log.setup_logging instead of
logging.getLogger directly, as setup_logging attaches a NullHandler by
default.
Collapse the docs into a single document.
There were only two places where openstacksdk was already logging to
something other than 'openstack'. Collapse those down to 'openstack'
until we come up with a reason to break them out more logically.
