google-batch provider % logging missing default

[rivershah]

With the recent google-batch provider, I am noticing that any stdout / err with % is broken. Maybe it is parsed as old style strings?

For example when I print nvidia-smi which shows % gpu usage, I see this:

0% is accurate but 0%!D(MISSING)efault is not

Thanks for reporting @rivershah . I'm able to reproduce something similar this with a quick test:

dsub \
   --provider google-batch \
   --project "${MY_PROJECT}" \
   --logging "${MY_BUCKET}" \
   --regions us-central1 \
   --command 'echo "%hel%lo%"'

In the resulting stdout file I see:
%!h(MISSING)el%!l(MISSING)o%!

Will update here as I learn more.
