[FEATURES]How cache workers are scheduled to computing nodes

[donghucey]

When the computing node does not have a cache worker，Scheduling cache workers to computing nodes can speed up training。Do you have relevant information?

@donghucey you can schedule data cache by specifying node affinity in Dataset.spec.

For example:

apiVersion: data.fluid.io/v1alpha1
kind: Dataset
metadata:
  name: demo
spec:
  mounts:
    - mountPoint: https://downloads.apache.org/hbase/stable/
      name: demo
  nodeAffinity:
    required:
      nodeSelectorTerms:
        - matchExpressions:
            - key: foolabel
              operator: In
              values:
                - "true"
