### _Why are the changes needed?_
This pr change two things:
1. add a config to kill executors if the plan contains table caches. It's not always safe to kill executors if the cache is referenced by two write-like plan.
2. force adjustTargetNumExecutors when killing executors. YarnAllocator` might re-request original target executors if DRA has not updated target executors yet. Note, DRA would re-adjust executors if there are more tasks to be executed, so we are safe. It's better to adjuest target num executor once we kill executors.
### _How was this patch tested?_
These issues are found during my POC
