Add support for UserCredentials for consumer

[Eugene Starchenko]

Sadly NACK does not work for jetstream consumers the way we use it 😔
the piece of code that looks up the credentials from the account object is missing for the consumer

nack/controllers/jetstream/consumer.go

Line 95 in 6c54a4e

 // FIXME: Add support for UserCredentials for consumer. 

here is the equivalent piece for the stream object (which works fine)

nack/controllers/jetstream/stream.go

Lines 110 to 132 in 6c54a4e

 	// Lookup the UserCredentials. 
 	if acc.Spec.Creds != nil { 
 		secretName := acc.Spec.Creds.Secret.Name 
 		secret, err := c.ki.Secrets(ns).Get(c.ctx, secretName, k8smeta.GetOptions{}) 
 		if err != nil { 
 			return err 
 		} 
  
 		// Write the user credentials to the cache dir. 
 		accDir := filepath.Join(c.cacheDir, ns, spec.Account) 
 		if err := os.MkdirAll(accDir, 0755); err != nil { 
 			return err 
 		} 
 		for k, v := range secret.Data { 
 			if k == acc.Spec.Creds.File { 
 				accUserCreds = filepath.Join(c.cacheDir, ns, spec.Account, k) 
 				if err := os.WriteFile(filepath.Join(accDir, k), v, 0644); err != nil { 
 					return err 
 				} 
 			} 
 		} 
 	} 
 }

Do you have a possible ETA for this case?
Thank you!

This should be fixed in #128
