support secondaryFiles for File in CommandInputRecordField

[liuxf09]

I have a input parameter that is an array of records, like the following:

resources:
  type:
    type: array
    items:
    - type: record
      name: resource
      fields:
        - name: resource
          type: File
          inputBinding:
            prefix: --resource
        - name: resource_param
          type: string
          inputBinding:
            prefix: --resource_param

In the record, resource is File object, and will require secondaryFiles. But secondaryFiles is only allowed for CommandInputParameter, and not allowed in CommandInputRecordField. Ideally I want to something like the following to work:

resources:
  type:
    type: array
    items:
    - type: record
      name: resource
      fields:
        - name: resource
          type: File
          secondaryFiles:
            - ".ext"
          inputBinding:
            prefix: --resource
        - name: resource_param
          type: string
          inputBinding:
            prefix: --resource_param

My reason to use array of records here is to combine resource and resource_param together to produce command line like --resource --resource_param --resource --resource_param.
One fix is to support secondaryFiles for File in CommandInputRecordField:
"In schemas/v1.0/Process.yml, there is a secondaryFiles field under Parameter. Just copy this field to under InputRecordField after label field. "
