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.

XenAPI: Tail output from stack.sh

While installing devstack in XenServer's DomU we can easily
track the output so end-users have much more visibility of
both what is going on and what (if anything!) went wrong.

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.

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.

Switch to Fedora-x86_64-20-20140618-sda

The heat-slow job using the Fedora-20 image as L2 guest, the
currently used version is affected by the heartbleed issue and
the Mb-Bios bug issue observed with emulation.

This version of the  Fedora cloud image uses the no_timer_check
kernel parameter, which solves the MP-Bios Bug issue.

The Image tested with ~3000 heat-slow job, without any issue.
