# == Class: cinder::glance
#
# Glance drive Cinder as a block storage backend to store image data.
#
# === Parameters
#
# [*glance_api_servers*]
#   (optional) A list of the glance api servers available to cinder.
#   Should be an array with [hostname|ip]:port
#   Defaults to $facts['os_service_default']
#
# [*glance_num_retries*]
#   (optional) Number retries when downloading an image from glance.
#   Defaults to $facts['os_service_default']
#
# [*glance_api_insecure*]
#   (optional) Allow to perform insecure SSL (https) requests to glance.
#   Defaults to $facts['os_service_default']
#
# [*glance_api_ssl_compression*]
#   (optional) Whether to attempt to negotiate SSL layer compression when
#   using SSL (https) requests. Set to False to disable SSL
#   layer compression. In some cases disabling this may improve
#   data throughput, eg when high network bandwidth is available
#   and you are using already compressed image formats such as qcow2.
#   Defaults to $facts['os_service_default']
#
# [*glance_request_timeout*]
#   (optional) http/https timeout value for glance operations.
#   Defaults to $facts['os_service_default']
#
# [*allowed_direct_url_schemes*]
#   (optional) A list of url schemes that can be downloaded directly via
#   direct_url.
#   Defaults to $facts['os_service_default']
#
# [*verify_glance_signatures*]
#   (optional) Enable image signature verification.
#   Defaults to $facts['os_service_default']
#
# [*glance_catalog_info*]
#   (optional) Info to match when looking for glance in the service catalog.
#   Only used if glance_api_servers are not provided.
#   Defaults to $facts['os_service_default']
#
# [*glance_core_properties*]
#   (optional) Default core properties of image
#   Defaults to $facts['os_service_default']
