If I make this a `JSON::Object`, the invocation site 
(https://reviews.apache.org/r/47216/diff/2#1) will do one extra copy (see the 
next section):
It would go:
-> `map<string, string>`
-> `map<string, JSON::Value>` 
-> `string`

Instead of:
-> `map<string, string>`
-> `string`

The parsing path remains unchanged, except there's one less `Try<JSON::Object>` 
in the executor's main.
I prefer the current flag type.

---

The conversion would look like:
```
map<string, string> task_environment = <something>;

JSON::Object json;
foreachpair (const string& key, const string& value, task_environment) {
  json.values[key] = value;
}
```
