Refactoring: Remove more legacy from release scripts.

Refactoring: Remove more legacy from release scripts.

- Remove an unused feature that allowed to check for required
  data before each script step.
- Use a relative path to the version file. In the production
  environment, this will point to the cwd/version_file, while
  in the test environment it is fake_cwd/version_file.

I guess this is historical, but * imports make it difficult to figure out where
things come from, like VERSION_FILE :(
