Allow setting deployment labels

To allow the velero backup system to do a slim restore of only userbackend data, the userbackend deployment needs to have a custom label. The chart doesn't currently allow for that.

changed milestone to %0.7.0

added Doing SSO labels

The existing labels are somewhat inconsistent by the way: the userbackend deployment has app.kubernetes.io/name=single-sign-on, while the corresponding pods have app.kubernetes.io/name=single-sign-on-userbackend. That should also be fixed but I'll probably leave that for another time.
