Improve OpenShift route configuration

[gsmet]

Notes from a Zulip discussion:

Having apparently unrelated config properties is an issue IMHO. I would rather have a route. config group with everything there.

Also:

• I couldn't find a way to make the route secure (and I would make it the default as it seems more sensible?)
• I think we should have route-specific annotations in the route. config group
• I had a weird error message because a route was already configured with another host name and the host name is immutable, maybe we could improve that

Something like:

...route.expose =
...route.host =
...route.annotations."value" =
...route.secure =

Also I don't know if it makes sense to allow to define several routes? Maybe it's not worth it?

+1 for moving all the relevant Route config into a dedicated root

I doubt it's worth it TBH
