Issue starting dockerbeat with ES_HOSTS

[jarkomes]

Hello,

We are getting an error when starting dockerbeat with the ES_HOSTS parameter in our docker run (our elasticsearch cluster is not running in docker and on other machines, so we use ES_HOSTS):
docker run --net bridge -m 0b --detach=true -e ES_HOSTS=xxx.xxxxxx.xxx.domain.tld -v /var/run/docker.sock:/var/run/docker.sock --name dockerbeat-app00 ingensi/dockerbeat:develop

Start error: loading config file error: YAML config parsing failed on dockerbeat.yml: yaml: unmarshal errors:
line 29: cannot unmarshal !!str xxx-xx... into []string. Exiting.

panic: close of nil channel

I @jarkomes ,

Try to set ES_HOST as following: `ES_HOST=["xxx:9200"]

There were a mistake in the README file, I just updated it 30 minute ago ;)
