extras: Provide group set for gluster-block workloads

For gluster-block workloads I/O is always with o-direct so it doesn't
benefit by any of the perf xlators so disabling all of them to save
on memory.
performance.quick-read=off
performance.read-ahead=off
performance.io-cache=off
performance.stat-prefetch=off
performance.write-behind=off
performance.open-behind=off
performance.readdir-ahead=off

We want the I/O on the file to be with o-direct
network.remote-dio=enable

Options that are proven to give good performance with
VM workloads which is very similar to gluster-block
cluster.eager-lock=enable
cluster.quorum-type=auto
cluster.data-self-heal-algorithm=full
cluster.locking-scheme=granular
cluster.shd-max-threads=8
cluster.shd-wait-qlength=10000
features.shard=on

It is better to turn off things we are not using
user.cifs=off

It is better to have allow-insecure to be on so that
ports that are > 1024 in tcmu-runner are allowed.
server.allow-insecure=on
