Xavi Hernandez 2b3e3ef08d extras: disable lookup-optimize in virt and block groups (#2254 )

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.

Fixes: #2253
Change-Id: I25861aa50b335556a995a9c33318dd3afb41bf71
