Forward AWS_ACCESS_KEY_ID & AWS_SECRET_ACCESS_KEY to worker hosts

[russki]

Super excited to see the support for env variables for authentication.

Would love to stop sending --s3key and --s3secret arguments in the jobs so that they're not showing up in --resfile & --csvfile files in plain text

But it doesn't seem like elbencho forwards these env variables to the worker --hosts

Is it possible to either

• stop writing out s3key/s3secret in resfile & csvfile in plain text?
  • maybe that can be behind an optional flag

or

• forward AWS_ACCESS_KEY_ID & AWS_SECRET_ACCESS_KEY to worker hosts automatically if they're set in the elbencho job run
