Issue 3306 - Create uplinks for pushing log files

modules/adblockplus/manifests/log/uplink.pp

+# == Type: adblockplus::log::uplink
+#
+# Used internally by class adblockplus::log::master to establish an SSH
+# uplink for each known server, both identifying and authenticating the
+# client by examining its $ip addresses and $ssh_public_key, i.e.:
+#
+#   # write into master:/var/adblockplus/log/uplink/$HOSTNAME/$@
+#   client# ssh -i /etc/ssh/ssh_host_rsa_key log@master $@ < log.1.gz
+#
+# Note the uplink itself being just an SSH layer for upstream I/O, meant
+# to become integrated as a client's post rotation command or similar.
+#
+# === Parameters:
+#
+# Identical to base::explicit_host_records.
+#
+# === Examples:
+#
+#   adblockplus::log::uplink {'example':
+#     ip => ['10.8.0.1'],
+#     ssh_authorized_key => 'AAA...',
+#   }
+#
