Current Situation

Currently this plugin only checks for updates for Homebridge, Homebridge UI, and plugins, but not for new Docker images.

Proposed Change

Be able to check and be notified of new Docker images available.

This would be useful for users that deploy Homebridge in a Docker container and only want to update Homebridge and Homebridge UI when a new Docker image is released. These users could then select to ignore Homebridge and Homebridge UI updates and be notified when a new Docker image is available.

Additional Context

Currently work is underway in the Docker HB repo to achieve the following:

• Each Docker image delivers a specific version of apt-pkg, which in turn defines specific versions of HB, HB UI, NodeJS, and FFMPEG. So a clean install of a particular Docker image will deploy a consistent and predefined environment, not whatever the latest versions happen to be at the time.
• Exposes the Docker image version, so HB UI can indicate when a newer Docker image is available.

This enhancement will need to wait until the changes to the Docker HB repo are completed and deployed.
