feat: add auto go maxprocs

[dongjiang1989]

What type of PR is this?

/kind feature What this PR does / why we need it: auto setting gomaxprocs

Which issue(s) this PR fixes: Fixes #

Special notes for your reviewer:

In Kubernetes env, the containers spec as follows:

  containers:
  - args:
    image: docker.io/karmada/karmada-scheduler:v1.12.2
    imagePullPolicy: IfNotPresent
    resources:
      limits:
        cpu: "4" 
        memory: 8Gi
      requests:
        cpu: "4"
        memory: 8Gi

In Runtime Information of Prometheus:

GOMAXPROCS:  96   // The host CPUs number, I'd like to see the values of `containers.requests` 4

In this case, the Go program scheduling or GC pause may cost too long.

The library automaxprocs has solved the problem that Go programs cannot set GOMAXPROCS correctly in the case of Containers.

Does this PR introduce a user-facing change?:
