This PR removes the last usages of DynConnector and HttpConnector from the aws_smithy_client crate with their counterparts in aws-smithy-runtime-api and aws-smithy-runtime. It also introduces HttpClient to make HTTP connector selection a smoother process, and adds a runtime plugin that configures a default HttpClient so that Config doesn't have to do that.

The DnsService from aws-config is also moved into aws-smithy-runtime and refactored to be consistent with the other configurable traits in the orchestrator since it will likely be used in the future for more than just the ECS credentials provider.

I still need to write changelog entries and apply the breaking-change label, but otherwise, this should be ready for an initial round of review.

The changelog entries and upgrade guidance are now in place. I think I incorporated all the feedback above, or explained why I'm punting on it.

effectively lgtm, but I expect that there will be one more pass

maybe we should add derive(Hash) to settings to make this cleaner

I was worried that could tie our hands in some way.

I think this structure has to be Hash if we expect people to use it as a cache key

operation-level timeouts didn't work before this right? Seems like we should add an integration test to capture that if we didn't already

I don't know what gave you the impression operation timeouts weren't working. We have integration tests for all the varieties of timeouts: https://github.com/awslabs/smithy-rs/blob/0af7920eba8d8d0dac79035c862e1dde1b377afc/aws/sdk/integration-tests/s3/tests/timeouts.rs

none of those tests change the HTTP connector timeouts for an individual operation (and I don't think we possibly could have supported that because we didn't have a cache keyed on http configuration)

mod async_impls {
use aws_smithy_async::rt::sleep::{AsyncSleep, SharedAsyncSleep};
use aws_smithy_async::time::{SharedTimeSource, TimeSource};
impl_shared_conversions!(convert SharedAsyncSleep from AsyncSleep using SharedAsyncSleep::new);

side note: we should rename the new methods to be something like new_from_unshared so they don't get called by accident and we have a place to guide folks to the into_shared() method

Maybe I'm not understanding your concern correctly, but I don't think I agree.

if you call SharedAsyncSleep::new and pass it something that's already a SharedAsyncSleep, you won't take advantage of the magic, right?

A fantastic piece of work, including docs and the upgrade guide ❤️ (for aws-smithy-runtime/src/client/http/test_util/* I only skimmed through them)
