What would you like to be added:
Performance improvement for create deployment.

Why is this needed:
When I create a deployment on the karmada control plane and wait until all pods under the deployment are running (the image has been pulled to the local host in advance), then create the next deployment. Each deployment is delivered to two clusters with 10 pods in each cluster. In this way, 150 deployments (totaling 3000 pods) are created cyclically, The total time is about 3 minutes. It takes about 1 minute to create 150 deployments (totaling 3000 pods) in a single cluster, It is expected that the performance of creating deployments in karmada is similar to that of a single cluster.
