Remove more unnecessary IMDS request logging

[rifelpet]

Ref: #16837 (comment)

Here is the call stack leading to the logging statement:

kops/vendor/github.com/aws/aws-sdk-go-v2/config/load_options.go

Lines 912 to 917 in 323dbae

	func WithClientLogMode(v aws.ClientLogMode) LoadOptionsFunc {
	return func(o *LoadOptions) error {
	o.ClientLogMode = &v
	return nil
	}
	}

kops/vendor/github.com/aws/aws-sdk-go-v2/aws/logging.go

Lines 16 to 21 in 323dbae

	type ClientLogMode uint64
	// Supported ClientLogMode bits that can be configured to toggle logging of specific SDK events.
	const (
	LogSigning ClientLogMode = 1 << (64 - 1 - iota)
	LogRetries

kops/vendor/github.com/aws/aws-sdk-go-v2/aws/logging.go

Lines 36 to 39 in 323dbae

	// IsRetries returns whether the Retries logging mode bit is set
	func (m ClientLogMode) IsRetries() bool {
	return m&LogRetries != 0
	}

kops/vendor/github.com/aws/aws-sdk-go-v2/feature/ec2/imds/request_middleware.go

Lines 112 to 115 in 323dbae

	return retry.AddRetryMiddlewares(stack, retry.AddRetryMiddlewaresOptions{
	Retryer: options.Retryer,
	LogRetryAttempts: options.ClientLogMode.IsRetries(),
	})

kops/vendor/github.com/aws/aws-sdk-go-v2/aws/retry/middleware.go

Lines 402 to 405 in 323dbae

	func AddRetryMiddlewares(stack *smithymiddle.Stack, options AddRetryMiddlewaresOptions) error {
	attempt := NewAttemptMiddleware(options.Retryer, http.RequestCloner, func(middleware *Attempt) {
	middleware.LogAttempts = options.LogRetryAttempts
	})

kops/vendor/github.com/aws/aws-sdk-go-v2/aws/retry/middleware.go

Lines 74 to 79 in 323dbae

	func (r Attempt) logf(logger logging.Logger, classification logging.Classification, format string, v ...interface{}) {
	if !r.LogAttempts {
	return
	}
	logger.Logf(classification, format, v...)
	}

kops/vendor/github.com/aws/aws-sdk-go-v2/aws/retry/middleware.go

Lines 204 to 205 in 323dbae

	r.logf(logger, logging.Debug, "retrying request %s/%s, attempt %d",
	service, operation, attemptNum)

The empty / in the log is because the IMDS client doesn't use the typical service + operation scheme for its requests.
