Phased releases of experimentalIdentityAndAuth for JSv3

[syall]

Announcement

Smithy (a language for defining services and SDKs) and smithy-typescript (generic Smithy TypeScript code generators) are both used to generate the AWS SDK for JavaScript v3.

As part of enhancing JSv3, the smithy-typescript experimental feature flag experimentalIdentityAndAuth will be enabled for JSv3 clients, and will release in phases. With this feature flag enabled, services will be able to define multiple authentication schemes and be aligned with the Smithy authentication traits specification.

These changes are designed to be completely backward compatible. If there are any unexpected issues related to identity, authentication, signing that seem related, please open a bug report.
