Add toString to req.body.ID of consul.agent.service.register

[Sayalic0]

consul.agent.service.register({
    "name": "casperx-manager",
    "id": 9939, // <= an interger
    "port": 9939,
    "address": "127.0.0.1",
    "check": {
        "http": "http://localhost:" + 9939 + "/health",
        "interval": "5s"
    }
}, function (err) {
    if (err) {
        console.log(err);
        throw err;
    }
});

That will result a 400 bad request, because consul require a String id. So I add toString() to make sure req.body.ID is a String.

Thanks for the PR, but I'd prefer if people just normalize options before calling consul. Implicitly coercing data generally causes more problems than it solves (at least in my experience).

Thanks again!
