Doesn't delete temporary directories after Workflow execution

[michael-kotliar]

Expected Behavior

After execution of a Workflow, all of the temporary folders should be deleted

Actual Behavior

When running Workflow (not CommandLineTool) after calling
builder = self._init_job(job_order, **kwargs)
the following temporary directories are created
builder.outdir
builder. tmpdir
builder.stagedir
but only
builder.outdir
is deleted after Workflow execution. Which causes huge amount of empty folder in /tmp
