processors as exported resources

[philmes]

I'd like to be able to add processors as exported resources, like you can with inputs. This would me to define filebeat in a base profile, and then add configuration from roles. For example:

To add inputs I can do this:

    filebeat::input { 'rails-api-logs':
        paths    => [
            '/blah/production.json.log'
        ],
        doc_type => 'syslog-beat',
        fields => {
            type => 'rails',
            app => 'api'
        }
    }

Is it possible to do the same with processors? The obvious doesn't work:

    filebeat::processors { 'rails-api-processors':
        params => {
            "add_host_metadata" => "~",
            "add_cloud_metadata" => "~",
            "add_docker_metadata" => "~",
            "add_kubernetes_metadata" => "~",
            "decode_json_fields" => {
                "fields" => ["message"],
                "target" =>"\"\"",
                "overwrite_keys" => "true"
            },
            "rename" => {
                "fields" => [{"from" => "host", "to" => "server" }]
            }
        }
    }

We don't have a defined resource for a processor yet, but I like the idea. I'll add it to the todo list, though if someone has time and wants to submit a PR before I get to it that's fine too.
