A Velero process is setting up the Factory settings if a user is passing client burst and client qps parameters, so that later on if a KubeClient is requested from the Factory instance, KubeClient will have client burst and client qps parameters as intended. So if a user pass a client-burst or client-qps parameters those parameters will be added in the Factory settings of a main Velero process.

In Velero 1.14, Burst and QPS will change defaults from 30 and 20 to 100 and 100.
