Takashi Kajinami 3c89736ffe Restart only specific services after config change 
Currently we restart all swift services regardless of the config file
being updated. This is very redundant, because some config files affect
only specific services (eg. account-server.conf is used only by
account-* daemons).

This introduces new "sub" tags such as swift-account-service and limit
the services being restarted.

# Class swift::objectexpirer
#
# == 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 object expirer pipeline.
# Defaults to ['catch_errors', 'proxy-logging', 'cache', 'proxy-server']
#
# [*concurrency*]
# (optional) Number of replication workers to spawn.
# Defaults to $facts['os_service_default'].
#
# [*expiring_objects_account_name*]
# (optional) Account name used for expiring objects.
# Defaults to $facts['os_service_default'].
#
# [*interval*]
# (optional) Minimum time for a pass to take, in seconds.
# 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) Time elapsed in seconds before an object can be
# reclaimed.
# Defaults to $facts['os_service_default'].
#
# [*recon_cache_path*]
# (optional) Directory where stats for a few items will be stored.
# Defaults to $facts['os_service_default'].
#
# [*report_interval*]
# (optional) Report interval, in seconds.
# 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.
# 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 undef
#
# [*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 undef
#
# [*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 undef
#
# [*log_level*]
# (optional) Log level.
# Defaults to 'INFO'.
#
# [*log_facility*]
# (optional) Log level
# Defaults to 'LOG_LOCAL2'.
#
# DEPRECATED PARAMETERS
#
# [*auto_create_account_prefix*]
# (optional) Prefix to use when automatically creating accounts.
# Defaults to undef
#
