v1.9.0

Quite a significant change in this release. You're now able to manage multiple docker hosts, both local and remote (TCP, TLS or SSH) from the same plugin. You can also flag a host as read-only which gives you lots of powerful tools to manage your deployments.

This means that you can do things like manage your local development environment, a read-write staging environment, and a read-only production environment all from one agent. You can ask questions like 'why did my container crash in staging?', 'am I suffering memory pressure in production?', 'what differences are there between my staging and production environments?', 'give me an overview of the status of all my environments'.

It will still basically be plug and play with zero configuration for simple environments where you're just managing the local docker daemon, but also hopefully a game changer for administrators of production environments.
