# Module name: haproxy_cd
# Author: Arne Teuke (arne_teuke@ConfDroid.com)
# @summary  Define manages the proxies for haproxy_cd.
# @param [Array] haproxy_fqdn the fqdn of the haproxy server in question.
# @param [String] frontend_name the name for the frontend section rule.
# @param [String] frontend_order where the concat should appear in the file.
# @param [String] frontend_mode mode for the loadbalancer instance: http or tcp
# @param [String] fe_use_backend which backend to use. if left empty, the
#   default backend will be used.
# @param [String] fe_bind_mode which bind mode to use, i.e. to which interface
#   and port to bind.
# @param [String] backend_name the backend name  to be used for the rule.
# @param [String] backend_order the order for the backend name, so it will be
#   within the correct lb instance configuration.
# @param [String] fe_maxconn the maximum connections for the lb instance.
# @param [String] be_server_name set the name for the backend server
# @param [String] be_balance what kind of balance should be used
# @param [String] be_mode  which backend mode should be used
# @param [String] default_backend value for the default backend
# @param [String] be_option value for a backend option
# @param [String] fe_tcp_request value for a frontend tcp request
# @param [String] fe_http_request value for a frontend http request
# @param [String] fe_option  value for a frontend option
# @param [String] acl_rule_front value for a frontend acl rule
# @param [String] acl_rule_back value for a backend acl rule
# @param [Array] backend_configs array of values for the backend
# @param [String] be_stick_table value for the backend stickiness
# @param [String] be_stick_on value for th backend stickiness
# @param [String] be_http_check value for backend http check
# @param [String] be_http_request value for a backend http request
# @param [String] be_acl_rule  value for a backend acl rule
