## cd_haproxy::server::proxy.pp
# Module name: cd_haproxy
# Author: Arne Teuke (arne_teuke@ConfDroid.com)
# @summary  Define manages the proxies for cd_haproxy.
# @param  [string] 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 the 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 poort to bind.
# @param  [string] acl_rule an ACL rule to be inserted if required. Empty values
#   will not be populated.
# @param  [string]  acl_order the order where the acl rule should be inserted,
#   so it will be within the correct lb instance configuration.
# @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
