    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
