Jay S. Bryant 0395353c4b Move config-reference to configuration
It was discovered today that the 'config-reference' directory
was supposed to have been renamed to 'configuration'.  The doc
team was expecting it to be at that location so that they could
automatically link to it from contributor/index.html .

This patch just moves the directory.  I am going to be submitting
a subsequent patch that properly sets out the framework for the
additional directories so that we don't have addition problems
in the future.

Description of Spectrum Scale NFS volume driver configuration options
Configuration option = Default value Description
[DEFAULT]
gpfs_images_dir = None (String) Specifies the path of the Image service repository in GPFS. Leave undefined if not storing images in GPFS.
gpfs_images_share_mode = None (String) Specifies the type of image copy to be used. Set this when the Image service repository also uses GPFS so that image files can be transferred efficiently from the Image service to the Block Storage service. There are two valid values: "copy" specifies that a full copy of the image is made; "copy_on_write" specifies that copy-on-write optimization strategy is used and unmodified blocks of the image file are shared efficiently.
gpfs_max_clone_depth = 0 (Integer) Specifies an upper limit on the number of indirections required to reach a specific block due to snapshots or clones. A lengthy chain of copy-on-write snapshots or clones can have a negative impact on performance, but improves space utilization. 0 indicates unlimited clone depth.
gpfs_mount_point_base = None (String) Specifies the path of the GPFS directory where Block Storage volume and snapshot files are stored.
gpfs_sparse_volumes = True (Boolean) Specifies that volumes are created as sparse files which initially consume no space. If set to False, the volume is created as a fully allocated file, in which case, creation may take a significantly longer time.
gpfs_storage_pool = system (String) Specifies the storage pool that volumes are assigned to. By default, the system storage pool is used.
nas_host = (String) IP address or Hostname of NAS system.
nas_login = admin (String) User name to connect to NAS system.
nas_password = (String) Password to connect to NAS system.
nas_private_key = (String) Filename of private key to use for SSH authentication.
nas_ssh_port = 22 (Port number) SSH port to use to connect to NAS system.
nfs_mount_point_base = $state_path/mnt (String) Base dir containing mount points for NFS shares.
nfs_shares_config = /etc/cinder/nfs_shares (String) File with the list of available NFS shares.
