Matt Fischer bb1e3e67dc Cinder hooks support
This code moves all deps to an external class so that Cinder can be
installed with mechanisms besides packages (like venv or docker). This
also cleans-up the dependency tree by removing false or confusing
dependencies.

# == define: cinder::backend::gpfs
#
# Configures Cinder to use the IBM GPFS Driver
#
# === Parameters
#
# [*gpfs_mount_point_base*]
# (required) Specifies the path of the GPFS directory where Block Storage
# volume and snapshot files are stored.
#
# [*gpfs_images_dir*]
# (optional) Specifies the path of the Image service repository in GPFS.
# Leave undefined if not storing images in GPFS. Defaults to "None" via
# driver.
# Defaults to <SERVICE DEFAULT>
#
# [*gpfs_images_share_mode*]
# (optional) 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. Defaults to "None" via driver.
# Defaults to <SERVICE DEFAULT>
#
# [*gpfs_max_clone_depth*]
# (optional) 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. Defaults to "0" via driver implementation
# Defaults to <SERVICE DEFAULT>
#
# [*gpfs_sparse_volumes*]
# (optional) 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. Defaults to "True" via driver.
# Defaults to <SERVICE DEFAULT>
#
# [*gpfs_storage_pool*]
# (optional) Specifies the storage pool that volumes are assigned to. By
# default, the system storage pool is used. Defaults to "system" via driver.
# Defaults to <SERVICE DEFAULT>
#
# [*nas_host*]
# (optional) IP address or Hostname of the NAS system.
# Defaults to $::os_service_default
#
# [*nas_login*]
# (optional) User name to connect to NAS system.
# Defaults to $::os_service_default
#
# [*nas_password*]
# (optional) Password to connect to NAS system.
# Defaults to $::os_service_default
#
# [*nas_private_key*]
# (optional) Filename of private key to use for SSH authentication.
# Defaults to $::os_service_default
#
# [*nas_ssh_port*]
# (optional) SSH port to use to connect to NAS system.
# Defaults to $::os_service_default
#
# [*manage_volume_type*]
# (Optional) Whether or not manage Cinder Volume type.
# If set to true, a Cinde Volume type will be created
# with volume_backend_name=$volume_backend_name key/value.
# Defaults to false.
#
# [*extra_options*]
# (optional) Hash of extra options to pass to the backend stanza
# Defaults to: {}
# Example :
# { 'gpfs_backend/param1' => { 'value' => value1 } }
