Add job record cache between different session, convenient scheduling plug-in extension

[zishen]

What would you like to be added:

Can volcano-scheduler add job record cache between different session, convenient scheduling plug-in extension. Custom caching position can be in api.JobInfo.

Why is this needed:

Like NodeInfo struct in volcano-scheduler, it has a cache between different session. So that volcano-scheduler plugin can provide customized modification。

type NodeInfo struct {
	Name string
	Node *v1.Node

	...

	// Used to store custom information
	Others     map[string]interface{}
	GPUDevices map[int]*GPUDevice
        ...
}
