CLI: impose limits

[josephjclark]

A common problem is that a workflow runs fine in the CLI, but when its migrated to platform (v1 or v2) it starts breaking because of memory limits (dataclip size, runtime memory)

The CLI should:

• By default, impose the same limits as Lightning
• When it blows up due to limits, post a very friendly message saying how to disable the limits
• Provide options in workflow, arguments and env vars to set the limits
• Provide an easy means to disable all limits
• Provide an easy means to sync limits with a lightning project (or with keywords, like "community" or "pro"

This helps prevent problems when a perfect workflow in CLI needs to be re-written to work on platform.
