push: make pushkey part advisory

The current behavior (with bundle1) is to let the rest of the push succeed if
the pushkey call (phases, bookmarks) failed (this comes from the fact that each
item is sent in its own command).

We kept this behavior with bundle2, which is highly debatable, but let us keep
thing as they are now as a start. We are about to enforce 'mandatory' pushkey
part as 'mandatory' successful, so we need to marks parts as advisory to
preserve the current (debatable) behavior.
