Use the $SERVICE_HOST in backup_swift_url

The $SERVICE_HOST is used to specify the swift proxy endpoint,
the c-bak should use the same endpoint.

Update client-env to use openstackclient commands

Updated the only instance of a keystoneclient command, to
check if the identity service is enabled.

Use urandom for heat key generation

Reading from /dev/random can block an virtual machine
even for several minutes, when the entropy pool is empty at the read time.

I have doubts we really need to use /dev/random here.
Even the ssh-keygen uses /dev/urandom by default,
 so the /dev/random is a little bit overkill here.

Update neutron-adv-test to use openstackclient commands

There were a few references of keystoneclient in
exercises/neutron-adv-test.sh, this patch will change those
commands to their openstackclient equivalents.

use disable/enable_apache_site on Ubuntu

Using the specific Apache2 tools a2ensite and a2dissite
(used in the methods disable/enable_apache_site in lib/apache)
should be the preferred way to disable the default site and
to enable the horizon site.

Default RABBIT_HOST to be the SERVICE_HOST.

Using localhost for RABBIT_HOST can cause problems - particularly
on systems where IPv6 is partially broken and localhost resolves
to an IPv6 address.

The service should logically be running on SERVICE_HOST unless
otherwise overridden.

Neutron.conf is not setup unless q-svc is enabled

In a multi-node environment, a node may have the neutron-
openvswitch-agent running but not the neutron API server.
The agent uses neutron.conf as one of the configuration
files. Devstack sets up neutron.conf only when q-svc is
enabled. Neutron.conf also needs to be configured when
q-agt is enabled.

Edit docs to include git.openstack.org url

This patch proposes a change to clone the devstack repository from
git://git.openstack.org rather than https://github.com since git urls
are faster than https and put less loads on the server.

Devstack support for Neutron VPNaaS

Includes two enhancements to support VPNaaS and allow other
vendor implementation support. Goal is to provide a solution
for VPN .ini files until a more general solution can be defined
to handle all reference and vendor .ini files.

First, the /opt/stack/neutron/etc/vpn_agent.ini file is copied
to /etc/neutron, to allow the selected device drivers for agent
to be specified. Both reference and vendor implementations can
be uncommented in this file, prior to stacking.

Second, to allow vendor VPN implementations to provide an .ini
file to the agent at start-up time, an environment variable is
defined and can be set in the localrc to specify one or more
.ini files. The desire is NOT to include vendor settings in the
global vpn_agent.ini.

Set flag in Tempest enabling Ironic scenario tests

When Ironic has been configured as the backing compute driver,
set the corresponding flag in Tempest that will cause a corresponding
scenario test to run.

add an image_list tool

this is an interface from devstack to provide a more robust
listing of the possible image urls that we might ask for during
a devstack run. This allows tools like nodepool, or 3rd party CI
systems to precache all this content in advance.

download fedora x86_64 image if heat is enabled

clean up the logic around producing a valid cfn image for heat
testing. If heat is enabled, add the f20 x86_64 imageurl to the
list of images that we support, and set that as the tempest
orchestration image.

The crux of this change is left commented out for now because we
need a two phase update of nodepool content before we can move
away from the old image (otherwise fedora mirrors will kill us
with bad downloads).

Install fping package

Now, we can't use os-fping API by default because devstack doesn't
install the fping package.
This commit adds installing the package and enabling to use os-fping
API.
