Update to glusterfs 3.8.0

From http://blog.gluster.org/2016/06/glusterfs-3-8-released/

Gluster.org announces the release of 3.8 on June 14, 2016, marking
a decade of active development.

The 3.8 release focuses on:
- containers with inclusion of Heketi
- hyperconvergence
- ecosystem integration
- protocol improvements with NFS Ganesha

Contributed features are marked with the supporting organizations.

  Automatic conflict resolution, self-healing improvements (Facebook)

    Synchronous Replication receives a major boost with features
    contributed from Facebook. Multi-threaded self-healing makes
    self-heal perform at a faster rate than before. Automatic
    Conflict resolution ensures that conflicts due to network
    partitions are handled without the need for administrative
    intervention

  NFSv4.1 (Ganesha) - protocol

    Gluster's native NFSv3 server is disabled by default with this
    release. Gluster's integration with NFS Ganesha provides NFS
    v3, v4 and v4.1 accesses to data stored in Gluster volume.

  BareOS - backup / data protection

    Gluster 3.8 is ready for integration with BareOS 16.2. BareOS
    16.2 leverages glusterfind for intelligently backing up objects
    stored in a Gluster volume.

  "Next generation" tiering and sharding - VM images

    Sharding is now stable for VM image storage. Geo-replication
    has been enhanced to integrate with sharding for offsite
    backup/disaster recovery of VM images. Self-healing and data
    tiering with sharding makes it an excellent candidate for
    hyperconverged virtual machine image storage.

  block device & iSCSI with LIO - containers

    File backed block devices are usable from Gluster through iSCSI.
    This release of Gluster integrates with tcmu-runner
    [https://github.com/agrover/tcmu-runner] to access block devices
    natively through libgfapi.

  Heketi - containers, dynamic provisioning

    Heketi provides the ability to dynamically provision Gluster
    volumes without administrative intervention. Heketi can manage
    multiple Gluster clusters and will be the cornerstone for
    integration with Container and Storage as a Service management
    ecosystems.

  glusterfs-coreutils (Facebook) - containers

    Native coreutils for Gluster developed by Facebook that uses
    libgfapi to interact with gluster volumes. Useful for systems
    and containers that do not have FUSE.
