Feature - support section arguments

[simonasr]

Hi ;)
These changes will let you configure section parameters like <buffer tag, key1, key2> (solves #118)
For example: you can use this code to configure ElasticSearch output:

td_agent_match 'output_es' do
  type 'elasticsearch'
  tag 'logs.**'
  parameters(
    hosts: 'localhost:9200',
    logstash_prefix: 'fluent-${key1}.${key2}',
    'buffer tag, key1, key2' => {
      timekey: '1d'
    }
  )
end

This code will result configuration which will route logs to different indices based on specific keys in message.

<match logs.**>
  @type elasticsearch
  index_name elastic.${key1}.${key2}
  <buffer tag, key1, key2>
    timekey 1d
  </buffer>
</match>
