Fix the developer database deploy procedure so it includes the mysql database driver
Add Gluster to the list of protocols in the Management Server

Gluster can now be used for Primary Storage just like NFS. This change adds the
Gluster protocol to the Management Server:

    Infrastructure -> Primary Storage -> Add Primary Storage

And also add the option to create Primary Storage on Gluster when
following the 'Add Zone' wizard from:

    Infrastructure -> Zones -> Add Zone

Some screenshots and verification:

Gluster should store volumes in qcow2 format

By default all network disks are in RAW format. Gluster works fine with
QCOW2 which has some advantages.

Disks are by default in QCOW2 format. It is possible to run into
a mismatch, where the disk is in QCOW2 format, but QEMU gets started
with format=raw. This causes the virtual machines to lockup on boot.

Failures to start a virtual machine can be verified by checking the log
of the virtual machine, and compare the output of 'qemu-img info'.

In /var/log/libvirt/qemu/<VM>.log find the URL for the drive:

    -drive file=gluster+tcp://...,format=raw,..

Compare this with the 'qemu-img info' output of the same file, mounted
under /mnt/<pool-uuid>/<img-uuid>:

    # qemu-img info /mnt/<pool-uuid>/<img-uuid>
    ...
    file format: qcow2
    ...

This change makes passes the format when creating a disk located on RBD
(RAW only) and Gluster (QCOW2).
