Node module in Cluster Status should be removed

Created by: serenashe

Describe the bug As the node status is already shown on the left of Component Status, an additional Node module seems to be redundant. Besides, a node is not a component. The node module in Component Status should be removed.

To Reproduce Steps to reproduce the behavior:

1. Log in to the KubeSphere console.
2. Click Platform on the upper left corner,
3. Go to Monitoring & Alerting > Cluster Status > Overview.
4. You can see that the Node module is in Component Status.

Expected behavior The node module should be removed.
