Use LVM_VOLUME_CLEAR if set
There are a few CI efforts going on related to jobs that use the lvm
image backend for the libvirt driver in Nova. We don't want to waste
time zero'ing out volumes during CI runs, so we need a way to configure
nova to not clear the volumes in these jobs.
This change adds a variable used to set the CONF.libvirt.volume_clear
value in nova.conf. If the variable isn't set, Nova just uses the default.
This will be set to 'none' in the jobs that are going to use LVM.
