Add support for account switching

[wesharper]

Right now, if I want to switch between work and personal projects, it feels a bit awkward as I have to choose which gitbutler account to sign in with. Logging out and logging back in is too cumbersome, but it feels wrong to be using my work account on personal stuff and vice-versa, even if the git authentication is handled via credentials-manager.

Ideally, different accounts could store different user-level config (even different git configs) and I could switch them in the UI to change the "author" of the commit and throw errors/warnings if the logged in user cannot commit/push to the repo.

It would be cool if these accounts were linked in some way so that if you became a paid subscriber the benefits would be shared across your work and personal accounts as well

@Kimeiga at that point, you'd need Gitbutler accounts to be completely decoupled from git profiles, which I personally think makes some sense, but would likely require a bigger lift. Maybe it's the better long-term approach though...

I wasn't aware of this issue yet and thought I'd chime in sharing some thoughts.

Right now, login-credentials are stored in the keychain of the system and to do that, a basically arbitrary key is used to differentiate them.
If that key was configurable with Git configuration it should be a natural experience to configure multiple accounts and tie them to different repositories, just like one would when configuring Git users.

To me this could be the first issue of multiple that deal with making GitButler configuration consistent and more flexible, by leaning into the strengths of the Git configuration more.

I am running into the same issue, I'm not a git superstar at all, but I have my ssh config set up, and have no issue with git or gh cli taking the Hostname to choose the right ssh key.

With gitbutler, it'll say it can't authenticate the remote with that same private key when I try to set it up with 'Use existing SSH key' in the project settings 🤷🏼‍♂️

No matter how complex the setup, fetching and pushing should always work if this option is set (the default):

This will just invoke git itself, which typically runs ssh which in turn picks up all of its configuration. This may fail if this setup relies on environment variables that are only set in an interactive shell. In that case, it should work when running GitButler directly from a terminal that one would launch Git in.

I hope that helps.
