e2e-tests: add AbandonChange scenario

This change adds a new abandon scenario which is more common to see in
daily use compared to a delete change one. Most Gerrit users do not
have permission to delete a change. Moreover, users are more likely to
abandon the change than delete it. The newly added scenario also
supports the 'numberOfUsers' parameter.
