Add `kubectl attach` support for multiple types

To address this issue: https://github.com/kubernetes/kubernetes/issues/24857
the new `kubectl attach` will contain three scenarios depend on args:
1. `kubectl attach POD` :   if only one argument provided, we assume it's a pod name
2. `kubectl attach TYPE NAME` : if two arguments provided, we assume first one is resource we [supported](https://github.com/shiywang/kubernetes/blob/4770162fd3fd0d65ff95348c71683cf4c717141a/pkg/kubectl/cmd/util/factory_object_mapping.go#L285), the second resource's name.
3. `kubectl attach TYPE/NAME` : one argument provided and arg[0] must contain `/`, ditto

Is there any other scenarios I haven't consider in ?

for now the first scenario is compatible with changed before, also `make test` pass ✅ 
will write some unit test to test second and third scenario, if you guys think i'm doing the right way.
