As the end-user of NDS Labs, I should be able to access the console of running service via the CLI and / or REST API.

This task encompasses changes to the API server and CLI to support console access to running services.

User can access console of running service via CLI
Preconditions:

• User is logged in via CLI
• Stack exists and is running

Primary flow:

• ndslabsctl console stack-service-id
• User can interact with container as if they were natively executing commands from within (navigate, edit files, etc)

Alternative flows

• User can access console of multiple containers at the same time
• User can access the console of the same container in multiple sessions
• If stack is stopped during active session, terminal session is terminated
• Interaction with terminal continues current user session (i.e., token refresh)
