Subject: [PATCH 539/539] extras: disable lookup-optimize in virt and block
 groups

lookup-optimize doesn't provide any benefit for virtualized
environments and gluster-block workloads, but it's known to cause
corruption in some cases when sharding is also enabled and the volume
is expanded or shrunk.

For this reason, we disable lookup-optimize by default on those
environments.
