Currently ATC stats of the project is maintained by OpenStack wiki
but it looks better to manage it in the git repo.
While anyone can edit OpenStack wiki, all changes to the git repo
are reviewed before submitted.
This commit just converts all data from
https://wiki.openstack.org/wiki/I18nTeam/ATC_statistics
without any modifications.
The only exceptions are:
* username 'gael__' is escaped to 'gael\__'
in doc/source/at-stats/data/newton.csv
to prevent sphinx from interpreting it as a anonymous link
* The link of the diff in Mitaka cycle was wrong and
it was fixed in this commit.
