[libvirt] [PATCH] RFC: experimental libvirtd upstart job

[apevec at gmail.com]

From: Alan Pevec <apevec at redhat.com>

To install it, disable libvirtd sysv initscript:
    chkconfig libvirtd off
    service libvirtd stop

and enable libvirtd upstart job:
    cp  /usr/share/doc/libvirt-*/libvirtd.upstart \
        /etc/init/libvirtd.conf
    initctl reload-configuration
    initctl start libvirtd

Test:
    initctl status libvirtd
libvirtd start/running, process 3929
    killall -9 libvirtd
    initctl status libvirtd
libvirtd start/running, process 4047
