Validation error when importing docker definition file as hint

[samuell]

How to reproduce:

1. Create this tool definition file, echo.cwl:

   #!/usr/bin/env cwl-runner
   
   cwlVersion: "cwl:draft-3"
   
   class: CommandLineTool
   
   hints:
     - $import: echo-docker.yml
   
   inputs:
     - id: "text"
       type: [string]
       description: |
         the text to echo
       inputBinding:
         position: 1
   
   outputs: []
   
   baseCommand:
     - echo

2. Create this docker definition file, echo-docker.yml:

   class: DockerRequirement
   dockerPull: ubuntu:16.04
   dockerFile: |
     ### Base Image
     FROM ubuntu:16.04

3. Create this job input file:

   text: Hello, world!

4. Execute:

   cwl-runner --no-container echo.cwl echo_testjob.yml 

Output received:

```bash
/home/samuel/.pyenv/versions/2.7.11/bin/cwl-runner 1.0.20160427142240
Tool definition failed validation:
Validating hint `DockerRequirement`: could not validate field `id` because it is not recognized and strict is True, valid fields are: class, dockerPull, dockerLoad, dockerFile, dockerImport, dockerImageId, dockerOutputDirectory
could not validate field `name` because it is not recognized and strict is True, valid fields are: class, dockerPull, dockerLoad, dockerFile, dockerImport, dockerImageId, dockerOutputDirectory
```

Expected output:

Something else.

OS: Xubuntu 16.04 64bit
CWL Tool: 1.0.20160427142240
Python: 2.7.11

Hmm, seems to have strong connections to #52 ...

Even though we're on the path of deprecating draft-3, just testing your reproducible example and the workflow is completed successfully.

@mr-c can we close?

@manu-chroma Sure, can you paste the results when you close this issue?

My output using latest cwltool:
