Need to add `id` and `label` fields to all CWL's and tools

[stevekm]

All workflows, subworkflows, and CommandLineTool's (and other tools and workflow processes) should be tagged with labels like this;

vcf_to_maf:
    run:
        class: CommandLineTool
        id: vcf_to_maf
        label: vcf_to_maf

This will make the logs easier to parse in order to track the status of workflow tasks. Otherwise workflow tasks seem to be represent in logs with uninterpretable hash ID's that are largely impossible to trace back to any discernible CWL component. For some reason, both id and label fields are required, having only one of them does not propagate them into the logs.

These fields can be seen with the toil_track_utils.py script (https://github.com/mskcc/pluto/blob/master/toil_track_utils.py)
