Make `debug logs get` behave more intuitively

[kananb]

Summary of the Pull Request

A few facets to this PR:

1. Add an optional --out_dir parameter to specify where to download the logs.
2. Deprecate the --last and --all options, making them no-ops.
3. Update the behavior to now always download all available logs (see #3572).
4. Update the logs to the console to reflect the new behavior.
