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.

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.

Only search the lib dir for rpc_backend

The grep in rpc_backend uses . to search all files. Unfortunately
the current directory when the command is called is not the lib
directory, so change it to search the lib directory instead.
Without this fix the command is forced to grep all files under
devstack which could be very slow if one has downloaded large
images.
