shelve: add an "internal" extra

shelve: add an "internal" extra

Keeping shelve changeset around increase the risk of collision with normal
changesets. To prevent such collision and help with overall clarity, we add an
'internal' key in extra that mark the changeset as created by "shelve".

Node changes in tests are expected.
