Add Invite SPDashboard config

This is needed to test the creation of services with SPDashboard

@pablothedude This won't work this way I assume, because of all the {{ ansible vars}} in the serverapplication.yaml

Hi @phavekes , I was aware of that, but for me it's hard to reverse engineer all variables and a trial and error approach wouldn't be that effective because I know to little about Invite.

So if you could replace them with some sane defaults based on a development or acceptance config that would be very helpful.
