fly consul attach is missing a `--stage` and/or --wait-timeout flag

[thomasfr]

Describe the bug When trying to attach a consul cluster with fly consul attach --app <app-name> to an existing app with multiple machines in multiple regions it would be beneficial to be able to either set a --stage flag so a later fly deploy command could add the --wait-timeout flag, or otherwise enable to set the --wait-timeout directly to the fly consul attach command.
