Windows: [infrabox] Job failed: environment can only contain strings

[greggw124]

This happens with docker-compose and may also happen with docker (non-compose) on the Windows operating system.

I used a workaround in run.py to encode the secret and non-secret names and values to ascii rather than unicode. I am not sure if this is the correct fix or not.

e.g.
env[name.encode('ascii', 'ignore')] = get_secret(args, value['$secret']).encode('ascii', 'ignore')

Error:
