Sean Dague 7d4c7e09b4 remove docker from devstack
with I1c9bea2fdeebc4199c4f7d8fca4580a6fb7fed5b nova removed
docker from it's driver tree.

We shouldn't have driver support inside of devstack that's not
part of upstream projects (this has been a line we've been
pretty clear on with Neutron drivers in the past).

Remove docker driver accordingly.
