ECS_INSTANCE_ATTRIBUTES documentation is incorrect

[joshgarnett]

ECS_INSTANCE_ATTRIBUTES need to specified as a json object not a json array of objects. The following fails with the error: "Invalid format for ECS_INSTANCE_ATTRIBUTES. Expected a json hash"

ECS_INSTANCE_ATTRIBUTES=[{"environment":"dev"}, {"type":"web"}]

The correct format is:

ECS_INSTANCE_ATTRIBUTES={"environment":"dev", "type":"web"}

This is wrong in the README.md not at http://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-agent-config.html
