This change adds a new `archive` module to the Coder registry. It can be
used to archive user-data from pre-defined locations and restore it as
well.
Here we also explore:
- A new method of passing arrays from Terraform to Bash
- A new method of writing Bash scripts that minimizes the interaction
with terraform interpolation
- Extensive test-suite that not only tests that Terraform options can be
selected, but also the resulting script behaviors
