provison whole directory output to S3

[byb121]

it seems that s3cmd-plugin can not handle this:

outputs:
  result_data:
    type: Directory
    outputBinding:
      glob: $(inputs.exp_name)

  "result_data":{
    "path":"s3cmd://tmp/dstore_test/out/",
    "class":"Directory"
  }

Dockstore exits normally, but results folder is not provisioned to S3.
