FR: Warn only when not pushing private commits

[senekor]

Is your feature request related to a problem? Please describe.

I am using the megamerge worklow with some local-only and some public changes on parallel branches. I have a bookmark pointing to the local-only change so I can refer to it easily. I would like to jj git push my other bookmark(s) with the public changes, but jj hard-errors on the one bookmark with local changes.

Describe the solution you'd like

Only emit a warning with the list of bookmarks that weren't pushed, because they contain private commits. Still push the other bookmarks.

Describe alternatives you've considered

Maybe it's possible to configure a default push revset that excludes any bookmarks that contain private commits? I wouldn't know how to do that though.

I might also be holding it wrong™, please tell me if you have a different workflow for working with local-only and public changes in parallel, without running into this problem.

Additional context

repro steps:

# init temp repo with some remote
jj new -m a -r 'root()' ; jj bookmark create a --to @
jj new -m b -r 'root()' ; jj bookmark create b --to @
jj config set --repo "git.private-commits" '"description(\'b\')"'
jj new a b
jj git push

I think this could be done via a flag, which won't require major changes.

That sounds good. Ideally the first hard error also informs the users about that flag. I might try to add this if I find the time.
