Makes error message easier to understand.

If the host ip address is indeterminate while executing
stack.sh, an error message is displayed.  This error message
could be a source of confusion since it references localrc,
which is depreciated.

This patch makes the error message clearer and easier to
understand.  It does this by taking out the reference to
localrc.  It also points the user towards local.conf where there
are suggestions on how to set HOST_IP.

Remove unused package dependencies

* /sbin/vconfig command is not used by either nova or neutron.
* Now the AMQP carrot is not used, not even optionally by
  the oslo.messaging.
* python-gfalgs just referenced as a similar configuration style,
  by neutron.

Update openSUSE-13.1 dependencies

The package libxml2-python was replaced by python-libxml2 since 12.2.
Rather use mariadb instead of mysql-community-server since the package
receives far more attention.

cinder_driver_certs.sh always passes driver

In cinder_driver_certs.sh, the tests are run and output is
piped to "tee".  Currently, checking the exit code of this
command only checks that "tee" exited properly.  Using the
pipefail option for this script will ensure the entire
pipe succeeds before passing a driver.

Without setting these, they default to localhost which
works in the the gate, but may not work in all devstack
setups.

Add python-dev to general requirements

Package python-openstackclient depends on pycrypto, and pycrypto depends
on python-dev. Since python-openstackclient should be installed in any
case, python-dev should be in general requirements.

bring back oslo_clean

oslo_clean is still needed at this point, removing it was
premature, especially for upgrade testing.
