Do not run heat/tools/nova_create_flavors.sh

This script takes a long time to run which will affect tempest
run times. Instead of running this, example templates will be modified
to align with the default heat flavors.

Basic check for homedir permissions

Several guides suggest using data directories under your homedir,
rather than the default /opt area.  This is fine, but on RHEL6 and
similar distros homedirs are very restrictive 0700 permissions which
doesn't allow things like httpd to pass through to serve up files.

Even though stack.sh is taking over the host, changing permissions
automatically is not a nice idea.  So we just warn when it looks like
this is happening.

Set MYSQL_HOST parameter to better support multi-node mode.

When deploying openstack with multi-node mode,
mysql needs to be started by listening it's real ip, not localhost.
but devstack always use localhost to recreate databases that will
lead bellow errors.

Add pbr to devstack.

It's being used in all of the core projects, so we should install it
at the start so we can ensure that we don't break everything all at
once.

Check quantum status dependent on the plugin

There are Quantum plugins that do not require the use of an agent.
This patch relaxes the constraint in quantum-adv-test.sh by adding
the ability to customize the logic that verifies whether the test
can run or not, depending on the Quantum plugin of your choice.

Fixes bug #1177904

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.

Disable selinux for RHEL6

selinux locks down httpd which causes various issues for Horizon
working from git checkouts.  Dealing with selinux is more a deployment
than a development issue, so we just disable it for devstack.

Clean up horizon apache logs on unstack

It feels like the right think to do. Moreover it will avoid to display
horizon errors from a previous devstack run that would be displayed because
of the tail -f in start_horizon()

xenapi - cleanup

Add error on unitialised variable to the scripts. This way some issues
were identified. Also modify README with fresh variables. The patch
includes:
 - Add SWIFT_HASH to the README
 - Add XENAPI_CONNECTION_URL to the README
 - Add VNCSERVER_PROXYCLIENT_ADDRESS to the README
 - Introduce UBUNTU_INST_IFACE which is the OpenStack VM interface used
   for the netinstall. It defaults to eth3. Previously this parameter
   was set by the combination of HOST_IP_IFACE and the undocumented
   NETINSTALL_IP
 - get rid of NETINSTALL_IP
 - xenrc includes CLEAN_TEMPLATES
 - xenrc no longer tries to change directory
 - remove chrooting from prepare_guest.sh (STAGING_DIR was always / )
 - remove DO_TGZ variable from prepare_guest.sh
 - use arguments to call prepare_guest.sh, instead of env vars
 - Fix backslash escaping in prepare_guest_template.sh

NOTE: networking is about to be addressed in a separate change.

xenapi - use management network to reach OS VM

Devstack used the HOST_IP_IFACE to reach the OpenStack VM through ssh.
This patch changes this behavior, so that the IP address of the
interface connected to the management network will be used.
