Matt Fischer bb1e3e67dc Cinder hooks support

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::iscsi
#
# === Parameters:
#
# [*iscsi_ip_address*]
# (Required) The IP address that the iSCSI daemon is listening on
#
# [*volume_backend_name*]
# (optional) Allows for the volume_backend_name to be separate of $name.
# Defaults to: $name
#
# [*volume_driver*]
# (Optional) Driver to use for volume creation
# Defaults to 'cinder.volume.drivers.lvm.LVMVolumeDriver'.
#
# [*volume_group*]
# (Optional) Name for the VG that will contain exported volumes
# Defaults to $::os_service_default
#
# [*volumes_dir*]
# (Optional) Volume configuration file storage directory
# Defaults to '/var/lib/cinder/volumes'.
#
# [*iscsi_helper*]
# (Optional) iSCSI target user-land tool to use.
# Defaults to '$::cinder::params::iscsi_helper'.
#
# [*iscsi_protocol*]
# (Optional) Protocol to use as iSCSI driver
# 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 :
# { 'iscsi_backend/param1' => { 'value' => value1 } }
#
