allow download specification for zen builds download (#734)

- Feature: `zen builds download` now supports `--download-spec-path` to determine what content to download from a build
  - The unstructured format expects one line per file relative to the root with '/' as a path delimiter
  - The structured format uses JSon format and the `--download-spec-path` must have extension `.json` to enable structured input

        {
            "parts": {
                "default" : {
                    "files": [
                        "foo/bar",
                        "baz.exe"
                    ]
                },
                "symbols": {
                    "files": [
                        "baz.pdb"
                    ]
                }
            }
        }
