Open Stack

Now that groups in Gerrit and teams in Launchpad are functionally
separate, we've renamed the *-drivers groups in Gerrit to
*-milestone so as to make that separation more obvious. This new
naming pattern was chosen to underscore that these groups' focus in
Gerrit ACLs of official projects is approving patches to
milestone-proposed branches.

Feel free to follow up to this message or find us in
#openstack-infra should you have any questions.
