Add support for OVS l2 agent in XS/XCP domU.

 * Config doc: http://wiki.openstack.org/QuantumDevstackOvsXcp

 * The Open vSwitch agent needs to be deployed on domU but
   interact with a dom0 bridge.
 * Add a root wrapper and associated XenAPI plugin to allow the
   agent to execute networking commands against dom0 from domU.
 * Update ovs_lib mac address discovery to use ip_lib to
   ensure that discovery works even for bridges not local to
   the agent (i.e. dom0 bridges).  A bridge configured with
   a dom0 root wrapper will execute ip link on dom0.
 * Update ip_lib to use a root helper by default to ensure that
   the 'ip' command will execute on dom0.
 * Remove obselete rpm spec and installer for dom0 agent.
 * Credit where credit is due - the XenAPI plugin and its
   packaging were largely copied from nova.
 * Supports blueprint xenapi-ovs

Nicira plugin: List ports on network gateways

Bug 1183277

This patch adds a read-only attribute to the network gateway API
extension. This attribute will return the list of ports connected to
a gateway, including their segmentation types and ids.
This patch now adds joined load for a gateway's connections, thus
avoiding extra queries to the db.

Require oslo.config 1.2.0a2

Fixes bug #1182662

Commit 362bd7f switched us from using 'QUOTA' as a config file section
name to using 'quota'.

This broke backwards compatibility support for 'QUOTA' because the
version of oslo.config that has that compat support had not yet been
released. The gory details are summarized here:

Perform a sync with oslo-incubator.

This oslo-incubator sync pulls in a new log.py which will make quantum's
default log output format the same as nova, glance and cinder (once
cinder's corresponding oslo sync merges). This common log format
simplifies log indexing as part of CI and makes lives easier for
deployers.

This sync does add a requirement on six as jsonutils depends on it. It
updates install_venv_common.py to be python26 compatible. It also brings
in a bunch of recent python3 compatibility that was added to oslo.

conversion specifier for getting proper debug log.
