Description

The PR is aimed at updating the aws-swift-sdk dependency to 0.36.1. https://github.com/awslabs/aws-sdk-swift/releases/tag/0.36.1. Updating to this release has triggered several changes that need to be made in Amplify. The changes are as follows:

• Renaming HttpClientEngine -> HTTPClient
• Renaming HTTPClient (originally HttpClientEngine) protocol method from execute to send
• Migrating using HTTPBody to ByteStream from ClientRuntime
• Renaming ClientRuntime.URLQueryItem -> ClientRuntime.SDKURLQueryItem
• Removing the HTTP Client Engine override, since now aws-swift-sdk defaults to using Foundation API's. Important thing to note is that even though the override has been removed, the logic for the override is still in place. It was not removed, because the logic gives us a powerful method to switch/override HTTP clients from the SDK, in future or in testing.
• Since the SDK now now eliminated service client protocols and Amplify was relying heavily on it, we have mimicked the SDK implementation to keep using the protocol structure. (feat!: Eliminate service client protocols awslabs/aws-sdk-swift#1322)
• Updated integration and unit tests
