Migrate AWS SDK to v2

[gomesjason]

Is this a bug fix or adding new feature?

Feature

What is this PR about? / Why do we need it?

AWS SDK v1 is no longer being maintained. This change moves us off that SDK.

What testing is done?

• Validated that a storage other than 1 returns an error

"GRPC error" err="rpc error: code = InvalidArgument desc = storageType INTELLIGENT_TIERING expects storage capacity to be 1Gi"

• Validated incorrect INTELLIGENT_TIERING parameters bubbles up correct

"GRPC error" err="rpc error: code = Internal desc = Could not create volume... BadRequest: The file system creation request failed because the provided OpenZFSConfiguration was invalid. ReadCacheConfiguration is a required parameter for OpenZFS file systems with StorageType INTELLIGENT_TIERING. To create the file system, resend the request with the ReadCacheConfiguration parameter included.

• Validated that expand volume on an INTELLIGENT_TIERING filesystem fails

"GRPC error" err="rpc error: code = Unimplemented desc = Storage of StorageType INTELLIGENT_TIERING Filesystem can not be scaled"

• Dynamically provisioned a DUAL, INTELLIGENT_TIERING filesystem. Validated I could write to it, and it was mounted with IPv6.
• Ran E2E Tests
• Validated new error handling

"GRPC error" err=<
        rpc error: code = InvalidArgument desc = Delete Parameters is incorrectly formatted: 1 validation error(s) found.
        - missing required field, DeleteFileSystemInput.OpenZFSConfiguration.FinalBackupTags[0].Key.
