Issue 3305 - Introduce adblockplus::log::tracker and ::forwarder

modules/adblockplus/manifests/log.pp

 # == Class: adblockplus::log
 #
 # Default root namespace for integrating custom logging entities.
 #
 # === Parameters:
 #
 # [*ensure*]
 #   Whether associated resources are ment to be 'present' or 'absent'.
 #
+# [*name*]
+#   Used as label to connect adblockplus::log::tracker instances to class
+#   adblockplus::log::forwarder, defaults to 'adblockplus::log'.
+#
 # [*rotations*]
 #   A hash of adblockplus::log::rotation $name => $parameter items
 #   to set up in this context, i.e. via Hiera.
 #
+# [*trackers*]
+#   A hash of adblockplus::log::rotation $title => $parameter items
+#   to set up in this context, i.e. via Hiera.
+#
 # === Examples:
 #
 #   class {'adblockplus::log':
 #     rotations => {
 #       # see adblockplus::log::rotation
 #     },
+#     trackers => {
+#       # see adblockplus::log::tracker
+#     },
 #   }
