containerFactory: useRunc ? #5412

I would like to ask what is the function of this parameter. Will the performance decrease after running runc? If it is false, what is the underlying virtualization technology used by the function?

In my experience, runc outperformed docker client. If useRunc is false, it will use just the docker command.

@style95 It seems that using runc directly should be able to get a greater performance improvement, but if we replace the docker runtime with crun, kata, etc., maybe we should only use docker. We would test it.
