fix: build strings for complex types differently for Terraform/Packer commands

fix(terraform,packer,cli): build strings for lists and dicts differently

Simply str()'ing complex types does not create strings in the format that Terraform requires. I also tested and fixed dicts. The fixes apply to Packer as well.

Also mentioned in the docs are sets and objects. In my testing, the changes for map and list handle those as well. Makes sense; objects are dicts with defined keys, and sets are unique list's.
