This plugin provides native Docker instrumentation for monitoring and metrics collection, including: container status, container number, and container metrics via `docker ps`.

Purpose
Adding metrics-docker-info.rb with general information related to Docker (total number of containers, images, go routines, file descriptors...). These metrics mimics how telegraf gathers information from the docker plugin, and can be useful for people evaluating Sensu as source for their metrics.
In metrics-docker-stats.rb I have added two features:
io metric collection from docker virtual devices, in telegraf style also
Including some environment variables values into the metric (another feature from telegraf).
Also those changes performed on existing metric check (metrics-docker-stats.rb) are optional, so users won't be affected by including new flags into the checks
