Bug #22401

crunch-run --list (with no additional args) should not read from stdin
Description
crunch-run --list can be a helpful tool for an admin during troubleshooting. However, that currently hangs waiting to read an instance price list from stdin. crunch-run --list </dev/null works, but an admin should not need to remember that.
Propose changing the default mode to "don't read from stdin" (admin-friendly), and update arvados-dispatch-cloud to pass an additional argument (--stdin=prices?) to enable the price list update behavior.

Maybe decide based on stdin isatty?

Hm. That would address the interactive use case without changing the a-d-c end, although it could still leave surprising behavior for scripts to discover later. Although I don't have a specific problem in mind, I'm also a little worried that ssh/pty stuff could cause this to make the wrong choice eventually.
Given the self-deploy version sync situation, I think an explicit command line argument would be more friendly/predictable.
