[feature request]ResourceDistribution should consider configmapGenerator

[qixiaobo]

What would you like to be added:
ResourceDistribution should support other resource like configmapgenerator with Kustomize
Why is this needed:
In k8s, configmap only used as create.
This is not a good design.
So if we want to change configmap we should delete and then create [of course we should pay attention to check exists]
So we cannot just easily to add a configmap with a file.
Luckily Kustomize support this with configmapgenerator.
https://kubernetes.io/docs/tasks/manage-kubernetes-objects/kustomization/

Generating Resources
ConfigMaps and Secrets hold configuration or sensitive data that are used by other Kubernetes objects, such as Pods. The source of truth of ConfigMaps or Secrets are usually external to a cluster, such as a .properties file or an SSH keyfile. Kustomize has secretGenerator and configMapGenerator, which generate Secret and ConfigMap from files or literals.

configMapGenerator
To generate a ConfigMap from a file, add an entry to the files list in configMapGenerator. Here is an example of generating a ConfigMap with a data item from a .properties file

In this case we just want to copy secrets like ssl certs ,
we may not want to paste this to a yaml with format.

We just use this in agro-cd.
So it's a git-ops practise

[qixiaobo]

In short , k8s support apply -f to any resources include configmap and secret.
But you know configmap or secret usually import from a file
in yaml keep it's format may be difficult.
And this file may be supported by other team.
So we often create configmap like this

kubectl create configmap game-config --from-file=configure-pod-container/configmap/

This may break the gitops pipeline

@FillZpp Should we support this function in kubectl-kruise?

That's ok to me. @qixiaobo WDYT?
