Adds support for requesting Curation waivers from the CLI, bypassing a blocking policy. This feature depends on the system admin allowing waiver requests. The flow augments the curation audit command, and is effective only for interactive shells.

No effect if waivers are not allowed, or the terminal is in a non-interactive mode.
