Sean Dague 980d0fcd75 Change livesnapshot to true by default
Because of past qemu bugs we set this to default off and required a
workaround to enable it. However these issues appear to be fixed, and
we should enable this by default for people (with the ability to turn
it off if it's causing crashes in their environment). Metacloud/Cisco
has been running default this way the entire time without issue.

Nova now defaults to using the live snapshot feature of libvirt
when taking snapshots. This was previously disabled by default due
to crashes on load seen with older libvirt versions. It has been
used in production by many clouds, and appears stable in real
world environments. If you see crashes of guests during snapshots,
you can disable this with the ``disable_libvirt_livesnapshot``
config value in ``[workarounds]``.
