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.

#
# == Class: cinder::backend::quobyte
#
# Configures Cinder to use Quobyte USP as a volume driver
#
# === Parameters
#
# [*quobyte_volume_url*]
# (required) The URL of the Quobyte volume to use.
# Not an array as a Quobyte driver instance supports exactly one volume
# at a time - but you can load the driver more than once.
# Example: quobyte://quobyte.cluster.example.com/volume-name
#
# [*quobyte_client_cfg*]
# (optional) Path to a Quobyte client configuration file.
# This is needed if client certificate authentication is enabled on the
# Quobyte cluster. The config file includes the certificate and key.
#
# [*quobyte_qcow2_volumes*]
# (optional) Boolean if volumes should be created as qcow2 volumes.
# Defaults to True. qcow2 volumes allow snapshots, at the cost of a small
# performance penalty. If False, raw volumes will be used.
#
# [*quobyte_sparsed_volumes*]
# (optional) Boolean if raw volumes should be created as sparse files.
# Defaults to True. Non-sparse volumes may have a very small performance
# benefit, but take a long time to create.
#
# [*quobyte_mount_point_base*]
# (optional) Path where the driver should create mountpoints.
# Defaults to a subdirectory "mnt" under the Cinder state directory.
#
# [*volume_backend_name*]
# (optional) Allows for the volume_backend_name to be separate of $name.
# Defaults to: $name
#
# [*manage_volume_type*]
# (Optional) Whether or not manage Cinder Volume type.
# If set to true, a Cinde Volume type will be created
# with volume_backend_name=$volume_backend_name key/value.
# Defaults to false.
#
# === Examples
#
# cinder::backend::quobyte { 'quobyte1':
# quobyte_volume_url => 'quobyte://quobyte.cluster.example.com/volume-name',
# }
#
