Build retry loop for screen sessions

There is a timing window where we might lose the commands being
stuffed into screen because bash is spawning. In those cases, loop
around and try building screen sessions again.

use setup_install for django_openstack_auth

This is fundamentally a library. As such we should setup_install
so that we can possibly pin it, otherwise we *always* get the
git version instead.

Don't install openvswitch-datapath-dkms on newer kernels

On kernels >= 3.13 for Ubuntu, there is no need to install the
openvswitch-datapath-dkms package anymore. Consequently we don't need the
dkms package anymore, nor the linux headers.

Update the opendaylight devstack code to correctly check for this and make
the right decision.

While here, also utilize get_packages() and common code where possible.

Default cinder enable_v1_api to true

As of Juno, Cinder will be deprecating the Cinder V1 API and setting it
to not be enabled by default. We'll make it enabled in devstack to
continue tests while it's supported.

Always check keystone using http

The check to $service_port must be done using http. It's
$KEYSTONE_SERVICE_PORT that may use either the http or https protocol.

Add explicit libkrb5-dev dependency for keystone

needed to install some of the python libraries keystone uses (kerberos,
brought in by requests-kerberos).

soft-qemu handling with F20 could image

When the qume used with Linux image without
a para-virtualized timer, various timing issues can happen,
if the qemu process preempted in the wrong time, for example
at timer test.

The issues less like happens on low load, high core number
host system, but it can happen.

For soft qemu (TCG) generally recommended to explicitly disable the
timer check.

Pre-caching the Fedora `gate edition` image, which contains the
the no_timers_check option.

Add rhel7 as supported distro

rhel7 testing has been fairly stable with redhatci bot testing beta
and RC builds for some time.  Centos7 testing is now coming online
with the nightly builds.  Thus no need to require the unsupported flag
any more.
