* Flux 0.39.0+

InfluxDB support

`http.endpoint()` iterates over input data and sends a single POST request per input row to
a specified URL.

This function is designed to be used with `monitor.notify()`.

`http.endpoint()` outputs a function that requires a `mapFn` parameter.`mapFn` is the function that builds the record used to generate the POST request.
It accepts a table row (`r`) and returns a record that must include the
following properties:

* `headers`
* `data`

*For information about properties, see `http.post`.*

##### Function type signature

(
    url: string,
) => (mapFn: (r: A) => {B with headers: C, data: bytes}) => (<-tables: stream[A]) => stream[{A with _sent: string}] where C: Record
