Use service role instead of admin role for service users

Instead of using a full admin role to validate tokens just use the
service role. Change where possible, some services use the service user
for more then just token validation.

Fix: bug 1187768
Add support for setting extra networking configuration options.

Add support for generically setting arguments for OpenStack Networking
for both the server and agent. This is done using Q_SRV_EXTRA_OPTS for the
server, which let you place settings in the "OVS" or "LINUX_BRIDGE"
sections of the plugin configuration file. For the agent, two variables
are defined: Q_AGENT_EXTRA_AGENT_OPTS lets you set items in the "AGENT"
section of the plugin configuration file, and Q_AGENT_EXTRA_SRV_OPTS
lets you set things in the "OVS" or "LINUX_BRIDGE" sections of the
plugin configuration file.

Implements blueprint devstack-quantum-config.

Decrease the tempest build interval

Decreasing the build interval leads to faster state change detection,
so it will speed up the gating jobs.

It may increase the possibility of a "hidden" issues causes
indeterministic test results.

Correct InvalidInstanceID.NotFound test.

* exercises/euca.sh: The match filtering InvalidInstanceID.NotFound
is cleaned up to eliminate numerous leaning toothpicks, and now also
actually works. The previous version was incorporating literal
square brackets into the pattern where I think a character list
match may have been intended instead, but was not actually necessary
anyway.

Periodic formatting cleanup

This is the semi-irregular comment and docs cleanup.

No functional changes should be here although some code is moved in a
small attempt to sort functions and get things where they need to be.

Install agent packages when running the Nicira plugin.

This is necessary because currently the plugin uses the dhcp amongst
other agents.

nicira third_party configuration.

Enables the multibackend Cinder tests in tempest when useful.

The change adds in lib/tempest an optional dependency on the var
$CINDER_MULTI_LVM_BACKEND which, if set, enables the multibackend
tests in the tempest config.

allow overwriting of http_image in tempest.conf

the default http_image variable is an upstream cirros url in
tempest. However, in the gate this can cause flakey failures if
that has connection issues.

Ensure that we can override this from devstack-gate to be
something we are sure is going to work.

Fix the OVS version check to work with upstream master versions of OVS.

This patch adds two functions to check version strings in the toplevel
functions file. The openvswitch_agent then uses these to compare versions
when checking for tunneling support. The tunneling version check now
also takes into account upstream master versions of Open vSwitch, which
the previous version check always failed on.
