Motivation and Context

This adds TimeSource in SDK and service configs so we can effectively control time when executing requests with the SDK at the client level.

note: the breaking change is in a trait implementation of a struct we're going to delete, not a real breaking change

Description

  • Add SharedTimeSource and use it in SdkConfig / aws-config / ::Config
  • Wire up the signer and other uses of SystemTime::now() that I could find
  • track down broken tests

Testing

  • various unit tests that all still pass

Checklist

  • I have updated CHANGELOG.next.toml if I made changes to the smithy-rs codegen or runtime crates
  • I have updated CHANGELOG.next.toml if I made changes to the AWS SDK, generated SDK code, or SDK runtime crates

Looks good.

Should we also add #[deprecated]? You can also probably just remove it now...

Does this end up being a Box<Arc<...>> under the hood due to the ConfigBag implementation?

yeah (but so does every thing we put in the ConfigBag, unfortunately)

there is a little trickery we could do to avoid that double-allocation with the new load/store traits because they can offer an enum that exposes the internals of the object so the config bag can use the smart pointer directly. not sure if it's worth it

Is StaticTimeSource available in codegenScope?

…mode (#2762)

## Motivation and Context
Service config structs now only contain a
`aws_smithy_types::config_bag::FrozenLayer` in the orchestrator mode (no
changes for the middleware mode).

## Description
This PR reduces the individual fields of service configs to contain just
`FrozenLayer`. This makes service configs work more seamlessly with
runtime plugins in the orchestrator mode.

Note that service config _builder_ s still contain individual fields.
We're planning to make them just contain
`aws_smithy_types::config_bag::Layer`. To do that, though, we need to
make `Layer` cloneable and that will be handled in a separate PR. For
builders, the only change you will in the PR is that their `build`
method will put fields into a `Layer`, freeze it, and pass it to service
configs.

This PR is marked as a breaking change because it's based on [another
PR](#2728) that's also breaking
change.

## Testing
- [x] Passed tests in CI
