Add a "--force" flag to `bin/auth revoke`

Summary: Ref T13043. I'd like to replace the manual credential revocation in the Phacility export workflow with shared code in `bin/auth revoke`, but we need it to run non-interactively. Add a `--force` flag purely to make our lives easier.

Test Plan: Ran `bin/auth revoke --everywhere ...` with and without `--force`. Got prompted without, got total annihilation with.
