Issue 3825 - Replace Logstash setup with Fluentd

modules/adblockplus/manifests/log/master.pp

 # == Class: adblockplus::log::master
 #
-# A server setup to collect and pre-process (i.e. anonymize and combine)
-# log files using Logstash (https://logstash.net/) pipelines.
+# A server setup to collect and pre-process log files. This is still a stub,
+# the generated configuration corresponds to recent package defaults.
 #
 # === Parameters:
 #
-# [*uplinks*]
-#   A hash of $name => $parameters resembling the servers registry within
-#   file modules/private/hiera/hosts.yaml, which is used by default.
+# [*ensure*]
+#   Whether the master setup should be 'present' or 'absent', defaults
+#   to $adblockplus::log::ensure.
 #
 # === Examples:
 #
 #   class {'adblockplus::log::master':
-#     uplinks => {
-#       'filter1' => {
-#         ip => '10.8.0.1',
-#         ssh_public_key 'AAA...',
-#       },
-#     },
 #   }
