# == Class: nova::cinder
#
# Configures Cinder credentials to use by Nova.
#
# === Parameters:
#
# [*password*]
#   (optional) Password for connecting to Cinder services in
#   admin context through the OpenStack Identity service.
#   Defaults to $facts['os_service_default']
#
# [*auth_type*]
#   (optional) Name of the auth type to load (string value)
#   Defaults to 'password' if password is set
#
# [*auth_url*]
#   (optional) Points to the OpenStack Identity server IP and port.
#   This is the Identity (keystone) admin API server IP and port value,
#   and not the Identity service API IP and port.
#   Defaults to 'http://127.0.0.1:5000' if password is set
#
# [*timeout*]
#   (optional) Timeout value for connecting to cinder in seconds.
#   Defaults to $facts['os_service_default']
#
# [*project_name*]
#   (optional) Project name for connecting to Cinder services in
#   admin context through the OpenStack Identity service.
#   Defaults to 'services' if password is set
#
# [*project_domain_name*]
#   (optional) Project Domain name for connecting to Cinder services in
#   admin context through the OpenStack Identity service.
#   Defaults to 'Default' if password is set
#
# [*system_scope*]
#   (optional) Scope for system operations.
#   Defaults to $facts['os_service_default']
#
# [*username*]
#   (optional) Username for connecting to Cinder services in admin context
#   through the OpenStack Identity service.
#   Defaults to 'cinder' if password is set
#
# [*user_domain_name*]
#   (optional) User Domain name for connecting to Cinder services in
#   admin context through the OpenStack Identity service.
#   Defaults to 'Default' if password is set
#
# [*os_region_name*]
#   (optional) Sets the os_region_name flag. For environments with
#   more than one endpoint per service, this is required to make
#   things such as cinder volume attach work. If you don't set this
#   and you have multiple endpoints, you will get AmbiguousEndpoint
#   exceptions in the nova API service.
#   Defaults to $facts['os_service_default']
#
# [*catalog_info*]
#   (optional) Info to match when looking for cinder in the service
#   catalog. Format is: separated values of the form:
#   <service_type>:<service_name>:<endpoint_type>
#   Defaults to $facts['os_service_default']
#
# [*http_retries*]
#   (optional) Number of times cinderclient should retry on any failed http
#   call.
#   Defaults to $facts['os_service_default']
#
# [*cross_az_attach*]
#   (optional) Allow attach between instance and volume in different availability zones.
#   Defaults to $facts['os_service_default']
#
# [*debug*]
#   (optional) Enable DEBUG logging with cinderclient and os_brick
#   independently of the rest of Nova.
#   Defaults to $facts['os_service_default']
#
