Top-like interface for container metrics

`ctop` provides a concise and condensed overview of real-time metrics for multiple containers:

as well as an [expanded view][expanded_view] for inspecting a specific container.

`ctop` currently comes with built-in support for Docker; connectors for other container and cluster systems are planned for future releases.
