Add Keep to ResetOptions

[kkrime]

When running:

err = wt.Reset(&git.ResetOptions{ Mode: git.HardReset })

Untracked files are over written.

when running the git equivalent
git reset HEAD --hard

untracked files are left alone.

Also, when running:
wt.Checkout(&git.CheckoutOptions{Branch: plumbing.ReferenceName("refs/heads/main"), Force: true})
Untracked files are over written.

when running the git equivalent
git checkout main -f

untracked files are left alone.

I think that the behaviour should be the same, as untracked files are not apart of the repo and this is causing me issues with my work.

git checkout

As per official documentation the -f / --force:

This is used to throw away local changes and any untracked files or directories that are in the way.

Which should be the same behaviour as you get with Force. To keep the untracked files, use Keep instead.

git reset

We could explore adding a Keep option for Reset so they are largely aligned.

Renaming the issue to align with the gap we have in go-git.
