As admin I can use processDefinitionKey as context data when configuring log message format so that I can identity the process definition when reading log files.

Problem:
When reading log files, it is important to be able to trace back log messages to the process definition in the context of which they occurred. Currently it is possible to log processDefinitionId, however this is a generated UUID and hard to consume. Process Definition Key is human created.

Thought: is this a performance problem since the key is not always available?
