Description of problem:
------------------------

Sometime back when I was working on improving gluster performance for
hyperconverged vm store workload, I'd seen ~6-8K iops improvement with random
read fio test (run from 3 vms hosted on gluster volume).

Even Manoj (cc'd) reported better performance on gluster-block with
choose-local disabled.

We're proposing to disable the option in groups virt and gluster-block in light
of the above.
