Martin von Zweigbergk e6693d0f68 backend: let backend choose root change id ...

Our internal backend at Google uses a 32-byte change id, so I'd like
to make the backend able to decide the length. To start with, let's
make the backend able to decide what the root change id should
be. That's consistent with how we already let the backend decide what
the root commit id should be.
