bug: AWS environment variables are not handled properly

[qdzlug]

Describe the bug A number of users have reported issues using the AWS ENV variables w/o the fallback profile settings in ~/.aws. This is most likely a bug in the way the start_all.sh script builds out the environment files.

To Reproduce Steps to reproduce the behavior:

1. Clone a new env, setup venv.
2. Set AWS credentials in your environment.
3. Run start_all.sh
4. Script will bail out.

Expected behavior Script should work as expected for ENV variables as well as for the configuration file.

Your environment n/a

Additional context n/a
