/**
* Constructs an `Observable` for a particular HTTP request that, when subscribed,
* fires the request through the chain of registered interceptors and on to the
* server.
*
* This method can be called in one of two ways. Either an `HttpRequest`
* instance can be passed directly as the only parameter, or a method can be
* passed as the first parameter, a string URL as the second, and an
* options hash as the third.
*
* If a `HttpRequest` object is passed directly, an `Observable` of the
* raw `HttpEvent` stream will be returned.
*
* If a request is instead built by providing a URL, the options object
* determines the return type of `request()`. In addition to configuring
* request parameters such as the outgoing headers and/or the body, the options
* hash specifies two key pieces of information about the request: the
* `responseType` and what to `observe`.
*
* The `responseType` value determines how a successful response body will be
* parsed. If `responseType` is the default `json`, a type interface for the
* resulting object may be passed as a type parameter to `request()`.
*
* The `observe` value determines the return type of `request()`, based on what
* the consumer is interested in observing. A value of `events` will return an
* `Observable<HttpEvent>` representing the raw `HttpEvent` stream,
* including progress events by default. A value of `response` will return an
* `Observable<HttpResponse<T>>` where the `T` parameter of `HttpResponse`
* depends on the `responseType` and any optionally provided type parameter.
* A value of `body` will return an `Observable<T>` with the same `T` body type.
