Server wide configuration, accessing it from a process

We use a different server for each environment (QA - STG- PROD). We use BPMN processes. Is it possible to set a value in the server and access it from a process (eg. as a process variable)? So we don’t have to keep a server-specific (and sometimes private) value in the process definition and change it for each deployment. This would also make it possible for us not to keep secrets in our repository.

An example is a URL to a web service in the same environment and an auth token, for a REST connector.

We use a custom image based on the Camunda Tomcat Docker image.
