Migrate the etcd implementations of the operations to here

[kwok](https://github.com/kubernetes-sigs/kwok/tree/main/pkg/kwokctl/etcd) is a simulated k8s cluster.
which implements a subcommand to bypass apiserver and directly edit the etcd data of the simulated cluster.
- [kwokctl hack get](https://github.com/kubernetes-sigs/kwok/blob/main/pkg/kwokctl/cmd/hack/get/get.go)
- [kwokctl hack del](https://github.com/kubernetes-sigs/kwok/blob/main/pkg/kwokctl/cmd/hack/del/del.go)
- [kwokctl hack put](https://github.com/kubernetes-sigs/kwok/blob/main/pkg/kwokctl/cmd/hack/put/put.go)

I want to apply the same capabilities to an existing test cluster rather than a simulation cluster.
allows easier modification of test cluster data for simulation to verify control plane stability after upgrade/downgrade or chaos.

I want to add a subcommand that can directly edit the data from etcd and use it like `kubectl`.
