You should use native isolate variable support.

Then you don't need to make a template. It's used via the --path-variable that
is also usable for arguments.

That sounds good. I modified things and tried to pass in:
--path-variable MASTER chromium.perf.fyi
--path-variable SLAVE_NUM 1

but it fails with:

  File
"/repos/chromium-tools/build/slave/fake_slave/build/swarming.client/isolate.py",
line 153, in <genexpr>
    for k, v in path_variables.iteritems())
  File
"/repos/chromium-tools/build/slave/fake_slave/build/swarming.client/isolate.py",
line 130, in _normalize_path_variable
    raise ExecutionError('%s=%s is not a directory' % (key, normalized))
ExecutionError:
MASTER=/repos/chromium-tools/build/slave/fake_slave/build/src/chrome/chromium.perf.fyi
is not a directory


Looks like it expects a directory and always fails if it is not a dir. Is there
another way to pass in args?

Ah, it works with --extra-variable. Done.
