turn off eventlet.wsgi debug

eventlet's wsgi server has a debug mode. This triggers in 3 cases:

1) returning a stack trace to the user on 500 error
2) printing 'accepted'... on every wsgi request
3) printing timeout on time out scenarios

In a real OpenStack environment #2 is basically what we see, all
the time, on *every* request. This ends up adding a lot of log
spam at INFO level.

Future eventlet will use real python logging, which will let us
log the debug messages at DEBUG level, but until then we should
clean out the logs to be vaguely sane.

sync oslo-incubator log.py

bring log.py up to date, most importantly to bring over

I130b08b1b4b5a48ecfa6418e7576d2bae2884f9e

which removes the extra newlines that eventlet adds to all the
logs, due to the way it works with the common logger.

Cleanup KDS doc build errors

There were 2 types of errors being generated from KDS when
building docs with tox -e docs.

The first was resolved by adding new lines before and after
a list in a doc string.

The second was resolved by making sure the symbols stated in
__all__ were wrapped with quotes.
