As part of DistributedLog graduation, DistributedLog git repo is renamed to
'distributedlog <https://github.com/apache/distributedlog>' and moved to
gitbox, as what BookKeeper did a month ago.
While in BookKeeper user feels more effective and smooth to use Github
issue for issue management, I am proposing to also try DistributedLog's
issue management in Github issue as BP-9
