Introduce app-wide property for quarkus.cxf.tls-configuration-name

[dcheng1248]

Currently, to set the TLS truststore for a client, the quarkus property quarkus.cxf.client."client-name".tls-configuration-name must be set. In our use case, we have all the certificates gathered into one truststore but have several clients, and it can feel cumbersome to have to set the property for every client. It would help avoid repeated code if an app-wide property is introduced.

I would be happy to see if I can help implement this if you think it is worth doing but not high priority.
