[terraform] support moving state from one backend to another

### TL;DR

Auto-generate terraform `state rm` and `import` commands from resources that have been moved from one terraform entrypoint to another.

### Detailed design

It is possible to determine from a `terraform plan` which resources have been moved from one state to another state. We can use these details to automatically determine which `state rm` and `import` commands need to be run.

Blocker: how do we determine import ID programatically? (not sure there is an easy solution, may need to hardcode and only support a subset of all resources).
