 Provide a way to retrieve fallback credentials if a call to `provide_credentials` is interrupted. An interrupt can occur when a timeout future is raced against a future for `provide_credentials`, and the former wins the race. A new method, `fallback_on_interrupt` on the `ProvideCredentials` trait, can be used in that case. The following code snippet from `LazyCredentialsCache::provide_cached_credentials` has been updated like so:

 Fix `name` and `absolute` methods on `OperationExtension`.
-
 The older, [now removed](https://github.com/awslabs/smithy-rs/pull/2161), service builder would insert `OperationExtension` into the `http::Response` containing the [absolute shape ID](https://smithy.io/2.0/spec/model.html#grammar-token-smithy-AbsoluteRootShapeId) with the `#` symbol replaced with a `.`. When [reintroduced](https://github.com/awslabs/smithy-rs/pull/2157) into the new service builder machinery the behavior was changed - we now do _not_ perform the replace. This change fixes the documentation and `name`/`absolute` methods of the `OperationExtension` API to match this new behavior.
-
 In the old service builder, `OperationExtension` was initialized, by the framework, and then used as follows:
-
 ```rust
 let ext = OperationExtension::new("com.amazonaws.CompleteSnapshot");
-
 // This is expected
 let name = ext.name(); // "CompleteSnapshot"
 let namespace = ext.namespace(); // = "com.amazonaws";
 ```
-
 When reintroduced, `OperationExtension` was initialized by the `Plugin` and then used as follows:
-
 ```rust
 let ext = OperationExtension::new("com.amazonaws#CompleteSnapshot");
-
 // This is the bug
 let name = ext.name(); // "amazonaws#CompleteSnapshot"
 let namespace = ext.namespace(); // = "com";
 ```
-
 The intended behavior is now restored:
-
 ```rust
 let ext = OperationExtension::new("com.amazonaws#CompleteSnapshot");
-
 // This is expected
 let name = ext.name(); // "CompleteSnapshot"
 let namespace = ext.namespace(); // = "com.amazonaws";
 ```
-
 The rationale behind this change is that the previous design was tailored towards a specific internal use case and shouldn't be enforced on all customers.
