Breaking Changes:

• ⚠ (smithy-rs#1825) Bump MSRV to be 1.62.0.
• ⚠ (smithy-rs#1740, smithy-rs#256) The SDK, by default, now times out if socket connect or time to first byte read takes longer than
  3.1 seconds. There are a large number of breaking changes that come with this change that may
  affect you if you customize the client configuration at all.
  See the upgrade guide for information
  on how to configure timeouts, and how to resolve compilation issues after upgrading.

New this release:

• 🎉 (aws-sdk-rust#237, smithy-rs#1770) It is now possible to programmatically customize the locations of the profile config/credentials files in aws-config:

  use aws_config::profile::{ProfileFileCredentialsProvider, ProfileFileRegionProvider};
  use aws_config::profile::profile_file::{ProfileFiles, ProfileFileKind};
  
  let profile_files = ProfileFiles::builder()
      .with_file(ProfileFileKind::Credentials, "some/path/to/credentials-file")
      .build();
  let credentials_provider = ProfileFileCredentialsProvider::builder()
      .profile_files(profile_files.clone())
      .build();
  let region_provider = ProfileFileRegionProvider::builder()
      .profile_files(profile_files)
      .build();
  
  let sdk_config = aws_config::from_env()
      .credentials_provider(credentials_provider)
      .region(region_provider)
      .load()
      .await;

• 🐛 (smithy-rs#1740, smithy-rs#256) Setting connect/read timeouts with SdkConfig now works. Previously, these timeout config values
  were lost during connector creation, so the only reliable way to set them was to manually override
  the HTTP connector.
• 🐛 (aws-sdk-rust#620, smithy-rs#1748) Paginators now stop on encountering a duplicate token by default rather than panic. This behavior can be customized by toggling the stop_on_duplicate_token property on the paginator before calling send.
• 🐛 (smithy-rs#1747, @kastolars) The client Config now has getters for every value that it holds.
• 🐛 (smithy-rs#1822, @kevinpark1217) Fix regression where connect_timeout and read_timeout fields are unused in the IMDS client
• (aws-sdk-rust#625, @kevinpark1217) Ability to override the IMDS client in DefaultCredentialsChain
• 🐛 (smithy-rs#1656) Fix aws-sigv4 canonical request formatting fallibility.
• (smithy-rs#1890) Add test to exercise excluded headers in aws-sigv4.
