SageMaker Inference CrossEncoder endpoint.

To use, you must supply the endpoint name from your deployed
Sagemaker model & the region where it is deployed.

To authenticate, the AWS client uses the following methods to
automatically load credentials:
https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html

If a specific credential profile should be used, you must pass
the name of the profile from the ~/.aws/credentials file that is to be used.

Make sure the credentials / roles used have the required policies to
access the Sagemaker endpoint.
See: https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html
