Revert "Adds passthrough config for cinder rootwra

This reverts commit 908a9f5dfe4d7174612c37a59b2a7fb4bb30fd68.

This config file is empty by default and breaks the ability
to create cinder volumes with the following error from
oslo.rootwrap:

  No section: \'Filters\'\n'

Fix argparse issue for RHEL 6.5.

Since RHEL 6.5 uses Python 2.6, which lacks argparse,
they need to be installed to ensure that os-apply-config
and os-refresh-config work properly.

Add new sosreport element

Provide an element that enables support information to be generated
on a running tripleo server.

This would allow for targeted data collection in CI runs, and is a
generally useful tool for diagnosing failures in a remote tripleo
installation.

Move libvirt's qemu configuration dir to state fs

We need libvirt domain entries created by Nova in to persist across
image upgrades.  Otherwise, instances are effectively removed from the
hypervisor after a new image deploys with an empty libvirt config tree.
This registers /etc/libvirt/qemu as a stateful path and ensures persistent
domain configurations across upgrades.

This reapplies a previously reverted fix, this time including the proper
element-deps.
