feat: Add dry run for provisioners (#178)

* refactor: Rename ProjectParameter to ProjectVersionParameter

This was confusing with ParameterValue before. It still is a bit,
but this should help distinguish scope.

* Add project version resources table

* Allow project parameters to optionally have user and workspace

* Add dry run for provisioners

* Add resource detection on project import
