 * This is an additional config resolver layer for clients using the default
 * AWS regional endpoints ruleset. It makes the *resolved* config guarantee the presence of an
 * endpoint provider function. This differs from the base behavior of the Endpoint
 * config resolver, which only normalizes config.endpoint IFF one is provided by the caller.
 *
 * This is not used by AWS SDK clients, but rather
 * generated clients that have the aws.api#service trait. This includes protocol tests
 * and other customers.
 *
 * This resolver is MUTUALLY EXCLUSIVE with the EndpointRequired config resolver from
 * |@smithy/middleware-endpoint.
 *
 * It must be placed after the `resolveEndpointConfig`
 * resolver. This replaces the endpoints.json-based default endpoint provider.
