Features Added

• Added Body::take().
• Added continuation_token to PagerOptions.
• Added extensible request authorization and authentication challenge handling to BearerTokenAuthorizationPolicy.
  • OnRequest, OnChallenge, and Authorizer traits define callbacks for these features.
  • with_on_request() and with_on_challenge() builder methods set callbacks for a policy instance.
• Added Request::body_mut().
• Added UrlExt::set_query_pair() to simplify overwriting query parameter key values.
• Sort query parameters lexicographically in QueryBuilder.

Breaking Changes

• Added type parameter C to Pager declaration, defaulting to Url so it can be elided in most existing declarations.
• Changed Pager::from_callback to take a PagerOptions as the second parameter rather than a Context parameter.
• Changed Pager::from_callback to Pager::new which now requires the caller to return a Pin<Box<dyn Future>>.
• Changed Poller::from_callback to Poller::new which now requires the caller to return a Pin<Box<dyn Future>>.
• Changed PollerResult::next field to PollerResult::continuation_token.
• Changed PollerState generic parameter from N to C.
• Moved BearerTokenAuthorizationPolicy into azure_core::http::policies::auth.
• Removed ItemIterator::with_continuation_token(). Pass a continuation token to PagerOptions::continuation_token instead.
• Removed PageIterator::with_continuation_token(). Pass a continuation token to PagerOptions::continuation_token instead.
• Removed Pager::from_stream.
• Removed Poller::from_stream.
• Renamed BoxedFuture to PagerResultFuture in pager module.
