Add Headers to HttpError

[PrestonGiorgianni]

Use Case

The api documentation for the api indicates that when you get a 429 rate limit, you should look at the Retry-After to determine when to try the request again. Currently influxClient.write will throw an error on 429 status codes, but I do not have access to this header to know how long to wait before a retry.

Expected behavior

try {
  influxClient.write(...)
} catch(error) {
  if (error instanceof HttpError && error.statusCode === 429) {
    error.headers['Retry-After'] !== undefined; //should be truthy
    // some back off logic based on error.headers['Retry-After']
  }
}

Actual behavior

try {
  influxClient.write(...)
} catch(error) {
  if (error instanceof HttpError && error.statusCode === 429) {
    error.headers['Retry-After'] !== undefined; //is falsy
    // some back off logic based on error.headers['Retry-After']
  }
}
