# == Class: nova::metadata
#
# Setup and configure the Nova metadata API endpoint for wsgi
#
# === Parameters
#
# [*neutron_metadata_proxy_shared_secret*]
# (optional) Shared secret to validate proxies Neutron metadata requests
# Defaults to undef
#
# [*metadata_cache_expiration*]
# (optional) This option is the time (in seconds) to cache metadata.
# Defaults to $::os_service_default
#
# [*local_metadata_per_cell*]
# (optional) Indicates that the nova-metadata API service has been deployed
# per-cell, so that we can have better performance and data isolation in a
# multi-cell deployment. Users should consider the use of this configuration
# depending on how neutron is setup. If networks span cells, you might need
# to run nova-metadata API service globally. If your networks are segmented
# along cell boundaries, then you can run nova-metadata API service per cell.
# When running nova-metadata API service per cell, you should also configure
# each Neutron metadata-agent to point to the corresponding nova-metadata API
# service.
# Defaults to $::os_service_default
#
# [*dhcp_domain*]
# (optional) domain to use for building the hostnames
# Defaults to $::os_service_default
#
# DEPRECATED
#
# [*enabled_apis*]
# (optional) A list of apis to enable
# Defaults to undef.
#
# [*enable_proxy_headers_parsing*]
# (optional) This determines if the HTTPProxyToWSGI
# middleware should parse the proxy headers or not.(boolean value)
# Defaults to undef.
#
# [*max_request_body_size*]
# (Optional) Set max request body size
# Defaults to undef.
