Improve the scheduler plugin for the actual production environment

[dashanji]

Describe your problem

The current scheduler plugin isn't enough to meet the needs of the actual production environment, we should improve the scheduler plugin to make it easy for end-users to use the vineyard's ability in the k8s environment.

What is the problem:

1. In the actual production environment, users need to align an order for a workflow.
2. At present, the CRD GlobalObject and LocalObject are considered observed resources, and we should get the workload that produces it through annotation or label and add ownereference for them.
3. There isn't a demo for users.

Todo List:

• [ ] Add some annotations for users to setup the workflow order etc.
• [ ] Add ownereference for GlobalObject and LocalObject.
• [ ] Containerize the current demo so that it can be deployed in the k8s cluster and used in the operator.
• [ ] Add an e2e test for the operator.
• [ ] Add user manual.

@sighingnow Could you please take a look at this?

I suggest design a tool kubectl vineyard or vineyardctl to interact with k8s, and to help user annotate their jobs or annotate vineyard objects.

Could you elaborate on it a bit here? If we only want to annotate an object or a job, the command kubectl annotate is enough.
