Rename commits to commitStatus to avoid confusion

MergeOp has a CommitStatus field named `commits` which is confused with
a `commits` field inside CommitStatus (there is also a private commits()
function). Besides, `commits` is not a good name a CommitStatus object.
I think I am just tired of seeing all those `commits` name.
