Review Comment:
This information is preserved and will be set in
`initFederationBlockTableJs`.
For the Federation page, as a user, I first want to know the running status
of the SubCluster, and then I care about the capacity information of the
cluster. I have made some changes to the information in the displayed list,
firstly showing
```
1.subClusterId
2.subClusterName
3.lastStartTime
4.lastHeartBeat
5.resources info
6.nodes info
```
When we click on the cluster id field, the metric information of the cluster
will be displayed, which are Application Metric, Resource Metric, and Node
Metric. When we click on the cluster id again, these information can be hidden,
and only the most basic SubCluster status is exposed.

> The Yarn Federation page before modification is as follows:
> enable federation:
> !image-2022-09-22-11-43-27-954.png|width=952,height=232!
> federation is not enabled
> !image-2022-09-22-11-49-10-974.png|width=958,height=209!
>
> The page needs to be optimized as follows:
> 1. Title is inaccurate, should be "About The Federation"
> 2.If the user does not configure federation.enable, the page should prompt
> information instead of showing blank.
> 3.For cluster information, we care more about the current sub-cluster status,
> registration time, heartbeat time, etc., rather than capacity information.
>
> enable federation:
> !image-2022-09-22-11-52-50-188.png|width=736,height=320!
> federation is not enabled
