New this release:

• 🎉 (smithy-rs#1457, @calavera) Re-export aws_types::SdkConfig in aws_config

• 🎉 (aws-sdk-rust#581) Add From<aws_smithy_client::erase::DynConnector> impl for aws_smithy_client::http_connector::HttpConnector

• 🎉 (aws-sdk-rust#567) Updated SDK Client retry behavior to allow for a configurable initial backoff. Previously, the initial backoff
  (named r in the code) was set to 2 seconds. This is not an ideal default for services like DynamoDB that expect
  clients to quickly retry failed request attempts. Now, users can set quicker (or slower) backoffs according to their
  needs.

  #[tokio::main]
  async fn main() -> Result<(), aws_sdk_dynamodb::Error> {
      let retry_config = aws_smithy_types::retry::RetryConfigBuilder::new()
          .max_attempts(4)
          .initial_backoff(Duration::from_millis(20));
  
      let shared_config = aws_config::from_env()
          .retry_config(retry_config)
          .load()
          .await;
  
      let client = aws_sdk_dynamodb::Client::new(&shared_config);
  
      // Given the 20ms backoff multiplier, and assuming this request fails 3 times before succeeding,
      // the first retry would take place between 0-20ms after the initial request,
      // the second retry would take place between 0-40ms after the first retry,
      // and the third retry would take place between 0-80ms after the second retry.
      let request = client
          .put_item()
          .table_name("users")
          .item("username", "Velfi")
          .item("account_type", "Developer")
          .send().await?;
  
      Ok(())
  }

• 🎉 (smithy-rs#1557, aws-sdk-rust#580) The imds::Client in aws-config now implements Clone

• 🐛 (smithy-rs#1541, @joshtriplett) Fix compilation of aws-config with rustls and native-tls disabled. The
  ProviderConfig::with_tcp_connector method uses
  aws_smithy_client::hyper_ext, which only exists with the client-hyper
  feature enabled. Add a feature enabling that, and enable it by default.

• (smithy-rs#1263) Add support for aws-chunked content encoding. Only single-chunk encoding is supported. Multiple chunks and
  chunk signing are not supported at this time.

• (smithy-rs#1540) Until now, SDK crates have all shared the exact same version numbers.
  This changes with this release. From now on, SDK crates will only version
  bump if they have changes. Coincidentally, they may share the same version
  number for some releases since changes to the code generator will cause
  a version bump in all of them, but this should not be relied upon.

• 🐛 (smithy-rs#1559, aws-sdk-rust#582) Remove warning for valid IMDS provider use-case

• 🐛 (smithy-rs#1558, aws-sdk-rust#583) Only emit a warning about failing to expand a ~ to the home
  directory in a profile file's path if that path was explicitly
  set (don't emit it for the default paths)

• (smithy-rs#1556) The sleep_impl methods on the SdkConfig builder are now exposed and documented.
