Open Stack

Hi,
I'd like to notify the Oslo community of these two changes to the oslo.log
section on the Oslo Wiki page:

1. There were conflicting statements about where bugs against oslo.log
should be created:
      - The CONTRIBUTING.rst file in oslo.log suggests:
      https://bugs.launchpad.net/oslo.log
      - The oslo.log section on the Oslo Wiki page mentions:
      https://bugs.launchpad.net/oslo
   Based on where bugs are currently open, I suspected that the information
   on the Oslo Wiki page would be outdated, and updated it accordingly.

2. There was no link to a source repo yet for oslo.log on the Oslo Wiki
page, so I added one to the github.com repo.

If any of that was a bad idea, please let me know.

Andy
