#
# Configures the swift proxy memcache server
#
# [*memcache_servers*] A list of the memcache servers to be used. Entries
# should be in the form host:port.
#
# [*tls_enabled*]
# (Optional) Global toggle for TLS usage when communicating with
# the caching servers.
# Default to $facts['os_service_default']
#
# [*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.
# Default to $facts['os_service_default']
#
# [*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.
# Default to $facts['os_service_default']
#
# [*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.
# Default to $facts['os_service_default']
#
# [*memcache_max_connections*] Sets the maximum number of connections to
# each memcached server per worker
