Fix container overriding output-dir/outputs

[sjmonson]

Summary

Ensure we are setting GUIDELLM_OUTPUT_DIR rather than GUIDELLM_OUTPUT_PATH in the container to allow --output-dir and --outputs to function. Additionally add a warning when environment variable are set.

Details

The container image sets GUIDELLM_OUTPUT_PATH=/results. Due to the way output-path interacts with the new output-dir and outputs options, output-path overrules their settings.

Test Plan

• Run container with --output-dir /test/path --outputs test.json,test.csv
