manage-vdi: Wait until devices have been created before mounting

kpartx creates partition devices asynchronously - it may exit before
the devices have been created.  This may cause a subsequent mount call
to fail, because the device it is trying to mount does not yet exist.
kpartx now has a -s option which makes it wait for the devices to be
created before returning, but the version XenServer's dom0 doesn't have
this option.   Work around this by retrying the mount.

When dom0's kpartx is updated, we will be able to use the -s option.

Update README for swift off by default

Change 11277b1f3cfa850c074d3effbb43987b6e6e6391 disabled swift due to
port conflicts but the documentation still states that it is enabled
by default, which can be quite confusing.

While we're there, wrap affected lines to 80 chars.

Set service_available config options in tempest

This commit loops over the list of services that tempest has config
options for in the service_available group and checks if the service
is enabled. Devstack will then set whether or not the service is
configured in tempest.conf.

Remove python-netaddr requirement

Remove python-netaddr as a DevStack (stack.sh) requirement,
this does not change any individual project requirements.

Specifically it replaces address_in_net() and adds cidr2netmask()
and maskip() functions.

Add ceilometer to the sys.path before the nova starts

The setup.py setup develop adds package to the
 /usr/lib/python2.7/site-packages/easy-install.pth.

The nova uses the ceilometer.compute.nova_notifier, so it must be
in the path before the nova started.

Fix various things when n-cell is enabled

1) Use the newer cell_type configuration option instead of overriding
the compute_api_class.

2) A nova-cells service is started for both the API cell (region) and
the compute cell (child).  The screen names were both 'n-cell' which
caused both services to log to the same log file.  The screen names have
been changed to n-cell-region and n-cell-child.

3) Security groups are not supported with cells.  Multiple exercises are
patched to use the 'default' security group instead of creating a new
one.  Additionally, if one uses the 'default' security group, do not try
to delete it, as one can never delete the default.

4) Disable the floating_ips and aggregates exercises when n-cell is
enabled, as they are not supported by cells.

5) Related to #4, disable the floating_ips tests within euca.sh

6) Update the README.md.  No services need to be disabled, and one only
needs to enable the n-cell service.

Set lock_path for Tempest to TMPDIR

Tempest change I5376f977a110f502f0e4958cbccbd379539e006b syncs
lockutils from oslo. Tempest with testr needs to use external locks
which require a lock_path config option. This commit sets that option
for tempest to use devstack's TMPDIR.

Update OpenVZ driver image

11.10 simply does not exist, so this simply does not work. However,
devstack-gate tries to pre-cache all images referenced, so even though
we're not doing anything with this, it's breaking devstack-gate.
