Adds default value for fixed_key

Adds a default value for fixed_key, for use by a key manager
implementation that reads the key from the configuration settings.
This single, fixed key proffers no protection if the key is
compromised.  The current implementation of the key manager does
not work correctly if the key is not set, so including this option
is helpful for Tempest testing and volume encryption within
DevStack.

Workaround missing zip snapshot

At the moment, xenserver installation depends on github snapshots.
Unfortunately, git.openstack.org does not have that capability. This
fix includes:

 - Exit with error code, if a download fails
 - create proper urls, even if they are using the git protocol
 - set git base to github - so we are able to do snapshots

Fix duplicated rootwrap.d in lib/ironic

The Ironic setup of devstack is duplicating the rootwrap.d directory at
/etc/ironic/rootwrap.d/rootwrap.d, this will cause the ironic-rootwrap
command to fail to execute. This patch is removing the duplicated
rootwrap.d directory.

Update cinder cert script to use run_tempest

Changes to tempest run_tests.sh
(commit: 17520e49a7e69b3817856a739121a1fb2906f2cc)
breaks the cinder_driver_cert script. A backward
compatible run_tempest.sh script was added,
so for now we should update the cinder_driver_cert
script to use that

updated sar options to collect more data

in order to have better data on the load state of the test nodes
we should track things beyond just cpu time. Add in load time,
process creation rates, and io rates during the tests.

also add a sar filter that makes it report on one line

reading sar input with multiple flags is somewhat problematic,
because it's tons of interspersed headers. So build something with
does a pivot filter to make it possible to get this all on one
line.

Make unstack.sh more like stack.sh

unstack.sh and stack.sh both have to "configure projects", but the

Keystone use common logging setup

The Keystone setup was using logging.conf to configure logging,
unlike other projects. This may have been left over from before
Keystone switched to oslo logging.

Switching to common logging configuration allows:
- Common format for logs for easier parsing
- Pretty colorized logs
- Keystone can control the default logging levels for libraries
  that are used by setting the defaults in keystone.
- Potentially using a function to setup logging for all components
  using oslo-logging (e.g., share with lib/nova).
