JSON to envdir tool

In goes json, out goes envdir.

JSON Format

{
  "name": "myapp",
  "env": {
    "MYVAR": "123",
    "MYVAR_TMPL": "{{.UUID}} 123",
    "MYVAR_HEX": "{{.HEX 32}} 123",
    ...
  }
}

Notice that you can have dynamic value for an env var. The format is in Go template. Currently {{.UUID}} and {{.HEX N}} are supported. HEX accepts an integer for length - the resulting string will be double this length.

Config File Format
