SDKs enpdoint prefix customization results in invalid request signatures.

[jasdel]

Confirm by changing [ ] to [x] below to ensure that it's a bug:

• I've gone though the API reference
• I've checked AWS Forums and StackOverflow for answers
• I've searched for previous similar issues and didn't find any solution

Describe the bug
When an API operation call is made with an operation that has an endpoint prefix, the request signature that is computed does not include that prefix. This results in an invalid signature

Version of AWS SDK for Go?
v0.28.0

Version of Go (go version)?
go1.15.1

To Reproduce (observed behavior)

_, err = client.ListJobs(context.Background(), &s3control.ListJobsInput{
	AccountId: &accountId,
}, func(o *s3control.Options) {
	o.APIOptions = append(o.APIOptions, func(stack *middleware.Stack) error {
		log.Println(stack.String())
		return nil
	})
})
if err != nil {
	log.Fatalf("request failed, %v", err)
}

Expected behavior
Successful request
