elasticsearch client timeout

When processing larger files, I was getting client timeouts. The default of 30 seconds wasn't enough. I ended up adding `requestTimeout: Infinity` to esConfig in shipElasticsearch.js: ``` var esConfig = { host: config.elasticsearch.host, requestTimeout: Infinity }; ``` I figure I don't really care about the client's timeout since Lambda has it's own timeout. Maybe this could be exposed as a config option?

Thanks, exposing the configuration makes sense to me.
