Move libvirt install + setup to functions-libvirt

Moves installation and setup of libvirt to a common functions-libvirt,
which can be used by other drivers in the future that may require
cross-distro libvirt installation and config but are not using
VIRT_DRIVER=libvirt (ie, Ironic).

Clean /etc/mysql when calling clean.sh

The clean.sh script should also remove the /etc/mysql
directory. It contains information from the old
devstack installation and may conflict with the further
one. apt-get purge does not remove it since the
directory is not empty.

Set correct default disk bus back to virtio on ppc64

virtio is supported and should be the default disk bus on Power to
take advantage of I/O performance drivers. This aligns with Nova
default bus values on PowerKVM. SCSI is the default for cdrom.

change the order of the print/flush

It seems that we get a different behavior whether stdout is closed
in the parent process or not when it comes to buffering. If it's
closed we don't get the last line flushed out to the file, if it's
not closed we do. This was seen in the trove pg fail.

A complete shot in the dark, but I'd like to see if this is fixed
with being explicit with printing to the log before stdout.
