# Class swift::containerreconciler
#
# == Parameters
#
# [*enabled*]
# (optional) Should the service be enabled.
# Defaults to true
#
# [*manage_service*]
# (optional) Whether the service should be managed by Puppet.
# Defaults to true.
#
# [*package_ensure*]
# (optional) Value of package resource parameter 'ensure'.
# Defaults to 'present'.
#
# [*pipeline*]
# (optional) The list of elements of the container reconciler pipeline.
# Defaults to ['catch_errors', 'proxy-logging', 'cache', 'proxy-server']
#
# [*interval*]
# (optional) Minimum time for a pass to take, in seconds.
# Defaults to $facts['os_service_default']
#
# [*concurrency*]
# (optional) Number of reconciler workers to spawn.
# Defaults to $facts['os_service_default'].
#
# [*process*]
# (optional) Which part of the work defined by $processes
# will this instance take.
# Defaults to $facts['os_service_default'].
#
# [*processes*]
# (optional) How many parts to divide the work into, one part per
# process. 0 means a single process will do all work.
# Defaults to $facts['os_service_default'].
#
# [*reclaim_age*]
# (optional) The reconciler will re-attempt reconciliation if the source
# object is not available up to reclaim_age seconds before it gives up and
# deletes the entry in the queue.
# Defaults to $facts['os_service_default']
#
# [*request_tries*]
# (optional) Server errors from requests will be retried by default
# Defaults to $facts['os_service_default']
#
# [*service_provider*]
# (optional) To use the swiftinit service provider to manage swift services,
# set service_provider to "swiftinit". When enable is true the provider
# will populate boot files that start swift using swift-init at boot.
# See README for more details.
# Defaults to $::swift::params::service_provider.
#
# [*memcache_servers*]
# (optional) A list of the memcache servers to be used. Entries should be in
# the form host:port. This value is only used if 'cache' is added to the
# pipeline,
# e.g. ['catch_errors', 'proxy-logging', 'cache', 'proxy-server']
# Defaults to ['127.0.0.1:11211']
#
# [*cache_tls_enabled*]
# (optional) Global toggle for TLS usage when communicating with
# the caching servers.
# Defaults to $facts['os_service_default']
# Default to false
#
# [*cache_tls_cafile*]
# (optional) Path to a file of concatenated CA certificates in PEM
# format necessary to establish the caching server's authenticity.
# If tls_enabled is False, this option is ignored.
# Defaults to $facts['os_service_default']
#
# [*cache_tls_certfile*]
# (optional) Path to a single file in PEM format containing the
# client's certificate as well as any number of CA certificates
# needed to establish the certificate's authenticity. This file
# is only required when client side authentication is necessary.
# If tls_enabled is False, this option is ignored.
# Defaults to $facts['os_service_default']
#
# [*cache_tls_keyfile*]
# (optional) Path to a single file containing the client's private
# key in. Otherwise the private key will be taken from the file
# specified in tls_certfile. If tls_enabled is False, this option
# is ignored.
# Defaults to $facts['os_service_default']
#
# [*log_name*]
# (optional) Log name.
# Defaults to $facts['os_service_default'].
#
# [*log_level*]
# (optional) Log level.
# Defaults to $facts['os_service_default'].
#
# [*log_facility*]
# (optional) Log level
# Defaults to 'LOG_LOCAL2'.
#
# [*purge_config*]
# (optional) Whether to set only the specified config options
# in the proxy config.
# Defaults to false.
