[midPoint] Where does one configure datasources in midPoint 4.0.2?

[Richard Frovarp]

I've read the documentation here:

https://wiki.evolveum.com/display/midPoint/Repository+Configuration#Rep
ositoryConfiguration-Datasourceconfiguration

But that doesn't give a current answer. Grepping through everything
looking for the bits I think might exist in files doesn't give me a
result. 

I'm getting a variety of connection problems, likely due to timeouts,
and it looks like the only way to set those is via a datasource.

Thanks,
Richard
