"Message too big" errors

[Dmitry Goloshubov]

We have found a lot of "Message too big" errors in the lma_collector.log like:
...
2016/02/18 16:16:52 Plugin 'elasticsearch_output' error: Message too big, requires 232605 (MAX_MESSAGE_SIZE = 196608)
...

Also, we've found the following information regarding this issue.
https://github.com/mozilla-services/heka/issues/1389

I see the workaround here could be increasing "max_message_size" setting in hekad.toml, [hekad] global section.

If you consider it appropriate, please include this to the plugin patch.
