Investigating support GraphQL

[hzxuzhonghu]

What would you like to be added:

FYI https://graphql.org/

GraphQL is a query language for your API, and a server-side runtime for executing queries using a type system you define for your data.

The benifit is Get many resources in a single request

As how to support GraphQL, i donot have a clear thought right now. Any comments are welcomed.

Why is this needed:

Currently, if we want to check a workload and its correslated resources, we must do many queries. With graphQL supported, this can be largely saved.
