Fix verbose flag

[LucasPickering]

Description

Describe the change. If there is an associated issue, please include the issue link (e.g. "Closes #xxx"). For UI changes, please also include screenshots.

Replace --verbose with --log-level. I forgot we're already using --verbose within the request subcommand. This also replaces the RUST_LOG env var.
