A future that will resolve to a DnsResponse upon completion

This indicates that the HTTP message was successfully sent, and we now have the response.RecvStream
If the request fails, this will return the error, and it should be assumed that the Stream portion of
this will have no date.
5.2. The HTTP Response
An HTTP response with a 2xx status code ([RFC7231] Section 6.3)
indicates a valid DNS response to the query made in the HTTP request.
A valid DNS response includes both success and failure responses.
For example, a DNS failure response such as SERVFAIL or NXDOMAIN will
be the message in a successful 2xx HTTP response even though there
was a failure at the DNS layer. Responses with non-successful HTTP
status codes do not contain DNS answers to the question in the
corresponding request. Some of these non-successful HTTP responses
(e.g., redirects or authentication failures) could mean that clients
need to make new requests to satisfy the original question.
Different response media types will provide more or less information
from a DNS response. For example, one response type might include
the information from the DNS header bytes while another might omit
it. The amount and type of information that a media type gives is
solely up to the format, and not defined in this protocol.
The only response type defined in this document is "application/dns-
message", but it is possible that other response formats will be
defined in the future.
The DNS response for "application/dns-message" in Section 7 MAY have
one or more EDNS options [RFC6891], depending on the extension
definition of the extensions given in the DNS request.
Each DNS request-response pair is matched to one HTTP exchange. The
responses may be processed and transported in any order using HTTP's
multi-streaming functionality ([RFC7540] Section 5).
Section 6.1 discusses the relationship between DNS and HTTP response
caching.
A DNS API server MUST be able to process application/dns-message
request messages.
A DNS API server SHOULD respond with HTTP status code 415
(Unsupported Media Type) upon receiving a media type it is unable to
process.
