Currently, Microprofile Code features a @RegisterRestClient annotation without a configKey attribute

Describe the solution you'd like

It would be great if this attribute was available, as it would make life a bit easier when integrating a generated microprofile artifact with an application.

Describe alternatives you've considered

Instead of having it configurable (preferred), generating a valid value for configKey would also be a way to go.
