Do a proper tls/ca cleanup in unstack

Certificates and the index were left in the data directory after
running unstack. That would break devstack on the next run.

Lower default IRONIC_VM_SPECS_RAM

Revert the default required RAM for Ironic nodes from 1024MB to 512MB.
Ironic now passes a kernel parameter to deploy ramdisks that avoids use
of tmpfs and lowers minimum memory requirements.

XenAPI: Use GUEST_PASSWORD when installing DomU

We know what the GUEST_PASSWORD will be, so set it during DomU
installation; therefore if the installation fails for any reason
we have a correct GUEST_PASSWORD set rather than the obscure and
undocumented 'r00tme'

XenAPI: Fix race condition on tailing stack.log

Stack.log is created by stack.sh, which is started by run.sh.  Using
the pid from run.sh doesn't mean that stack.log has been created yet
so wait for the log to be created before tailing

Make apache restarts a little more forgiving

Apache sometimes is slow to release the port (from the kernel's
perspective) which can cause restarts of apache to fail due to the
requested port already being bound. This fix introduces a small sleep
between the stop and start to help make apache deployments a bit
more resilient.

XenAPI: Always add latest Cirros euc image

Some tests, such as test_minimum_basic_scenario, assume qcow and if
a qcow image does not exit, falls back to the euc image.
This change ensures these tests work in the stock XenServer environment.

Fix default_volume_type for Cinder multi backend

The default_volume_type option doesn't support comma separated
arguments. We can only select one default volume type.
We have a variable that contains the default volume type, so we simply use it.

Add argparse for RHEL6

python2.6 doesn't have argparse, required by outfilter.py.  This
package is a dependency on cloud-init, so this problem is often masked
in many testing environments.

Add WSGISocketPrefix to apache keystone config

I think since probably fdf1cffbd5d2a7b47d5bdadbc0755fcb2ff6d52f
devstack on RHEL6 fails and it comes down to:
