Don't use enums, namespaces

[PuruVJ]

Some parts of our SDK uses enums and one specific part(UpdateStatus) uses namespaces as a runtime feature. These are non-standard TS-only features which are compiled to JS. The input and output are vastly different. This should be converted to a class like all other modules in client_api folder.

Compiled output:

var UpdateStatus;
((UpdateStatus2) => {
  function getAlgebraicType() {
    return AlgebraicType.createSumType([
      new SumTypeVariant("Committed", DatabaseUpdate.getAlgebraicType()),
      new SumTypeVariant(
        "Failed",
        AlgebraicType.createPrimitiveType(BuiltinType.Type.String)
      ),
      new SumTypeVariant("OutOfEnergy", AlgebraicType.createProductType([]))
    ]);
  }
  UpdateStatus2.getAlgebraicType = getAlgebraicType;
  function serialize(value) {
    switch (value.tag) {
      case "Committed":
        return { Committed: DatabaseUpdate.serialize(value.value) };
      case "Failed":
        return { Failed: value.value };
      case "OutOfEnergy":
        return { OutOfEnergy: [] };
      default:
        throw "unreachable";
    }
  }
  UpdateStatus2.serialize = serialize;
  UpdateStatus2.Committed = (value) => ({
    tag: "Committed",
    value
  });
  UpdateStatus2.Failed = (value) => ({ tag: "Failed", value });
  UpdateStatus2.OutOfEnergy = { tag: "OutOfEnergy", value: void 0 };
  function fromValue(value) {
    let sumValue = value.asSumValue();
    switch (sumValue.tag) {
      case 0:
        return {
          tag: "Committed",
          value: DatabaseUpdate.fromValue(sumValue.value)
        };
      case 1:
        return { tag: "Failed", value: sumValue.value.asString() };
      case 2:
        return { tag: "OutOfEnergy", value: void 0 };
      default:
        throw "unreachable";
    }
  }
  UpdateStatus2.fromValue = fromValue;
})(UpdateStatus || (UpdateStatus = {}));

enums deserve similar treatment
