Update httpcore requirement from ==0.9.* to >=0.9,<0.12

[dependabot]

Updates the requirements on httpcore to permit the latest version.

Release notes

Sourced from httpcore's releases.

Version 0.11.0

0.11.0 (September 22nd, 2020)

The Transport API with 0.11.0 has a couple of significant changes.

Firstly we've moved changed the request interface in order to allow extensions, which will later enable us to support features such as trailing headers, HTTP/2 server push, and CONNECT/Upgrade connections.

The interface changes from:

def request(method, url, headers, stream, timeout):
    return (http_version, status_code, reason, headers, stream)

To instead including an optional dictionary of extensions on the request and response:

def request(method, url, headers, stream, ext):
    return (status_code, headers, stream, ext)

Having an open-ended extensions point will allow us to add later support for various optional features, that wouldn't otherwise be supported without these API changes.

In particular:

• Trailing headers support.
• HTTP/2 Server Push
• sendfile.
• Exposing raw connection on CONNECT, Upgrade, HTTP/2 bi-di streaming.
• Exposing debug information out of the API, including template name, template context.

Currently extensions are limited to:

• request: timeout - Optional. Timeout dictionary.
• response: http_version - Optional. Include the HTTP version used on the response.
• response: reason - Optional. Include the reason phrase used on the response. Only valid with HTTP/1.*.

See encode/httpx#1274 for the history behind this.

Secondly, the async version of request is now namespaced as arequest.

This allows concrete transports to support both sync and async implementations on the same class.

Added

• Add curio support. (Pull #168)
• Add anyio support, with backend="anyio". (Pull #169)
