Add third-party support for Quantum NVP plugin

This patch leverages the third-party mechanism provided by DevStack
to customize the configuration of DevStack instances when working
with the Quantum NVP plugin. This is useful in dev/test scenarios,
where connectivity between the DevStack VM and the NVP Gateway is
required.

Set variables in rsyslog.conf to disable rate-limiting.

Per Bug https://bugs.launchpad.net/openstack-ci/+bug/1024487, this will
modify the rate-limiting setting for rsyslog.conf.  If rate-limiting is
being used the addition will set it to 0 otherwise the addition will
add the variables to the configuration file and set them to 0.

Implements: Variables "$SystemLogRateLimitBurst 0", and
"$SystemLogRateLimitInterval 0" in "/etc/rsyslog.conf". These changes
are persuent to what has been outlined in the rsyslog docs as found
here : http://www.rsyslog.com/tag/SystemLogRateLimitInterval/

Updated commit implements changes in code and placement post code
review. Recent change implements the "SystemLogRateLimitBurst" in first
if statement, which was "SystemLogRateLimitInterval" and wrong.

Add missing .debs required by Debian

xenapi: kernel_cmdline moved out from template

The kernel's cmdline was set during the initial devstack machine
installation. Thus, during second runs, the kernel's cmdline was not
updated. This patch extracts append_kernel_cmdline, and configures
domU's kernel cmdline every time. As some networking parameters are
passed through the kernel cmdline, this patch makes it possible to
change the network configuration, even if a cached devstack exists.

Moves Nova v3 API enable config to group

https://review.openstack.org/#/c/29487/ moves the Nova v3 API
enable flag into its own config group. And renames it to just
"enable". This changeset follows that change. As we do not yet
gate on any Nova V3 API tests we don't need to keep the old setting
around.

Use nova bindir of /usr/bin on Fedora

Fedora (and RHEL) like to install things in /usr/bin, e.g.

 01:30:42 Creating /usr/lib/python2.7/site-packages/nova.egg-link (link to .)
 01:30:42 Adding nova 2013.2.a1031.gfc5137d to easy-install.pth file
 01:30:42 Installing nova-dhcpbridge script to /usr/bin
 ...

The default nova/paths.py defaults to /usr/local/... which causes
quite a few errors when stressing various parts of nova and tools
aren't found.

Add Fake virt driver support

nova fake virt driver can be used to simulate running arbitrarily large
number of VMs.  When the fake virt driver is selected, all other arbitrary
limits are disabled (quotas, scheduler limitations) as well. The fake
virt driver can be selected by adding the following line to your localrc

      VIRT_DRIVER=fake

This setting can be used to do simulated large scale (as defined by
number of VMs) testing (such as boot 500 VMs at once) inside a single
devstack instance.

Source functions in rejoin-stack.sh

stackrc loads localrc and localrc can use functions
like enable_service and disable_service. Make sure
the functions are defined before loading stackrc.
