Pull docker images from global registry

The global docker registry is where images are
being built and uploaded. It's effectively docker's
version of, say, 'pip'. The static tarballs are
not only an extra maintenance burden as they're outside
the standard build and publishing process, but are presently
outside the scope of an open development / release
process as well.

While this process does cause some trouble with
network-independence for CI purposes, the fetching
is still done from install-docker.sh; Additionally,
this driver is not currently tested via the community CI effort.

LDAP root DN creation fails

When keystone is configured to set up an LDAP server to use as
it's identity backend, the creation of the root DN fails.  The
problem is that one of the mods in the modify operation that sets
up the root DN is incorrect, which causes the entire modify
operation to fail.  The incorrect mod is attempting to configure
some attribute indexes, but one of the attributes it specifies is
undefined.  This patch removes the undefined attribute from the
template that is used to create the modify operation.

use ext4 for guest default ephemeral

this isn't upstream default because of compatibility questions
with really old host on providers. However there is no reason not
to do it in devstack.

Have ceilometer to respect the keystone settings

lib/ceilometer ignored the global settings related to keystone settings.

It can cause issues for example when the keystone does not listen on
127.0.0.1 even in single node deployment.

glance just used to admin role for token validation,
the service role is sufficient for this.

glance also needs an user with enough permission to use swift,
so creating a dedictated service user for swift usage when s-proxy is
