What/Where is the issue ?

If a per-process definition key doesn't exist in the history cleanup configuration, the whole history cleanup will fail with a configuration exception. This means that correctly configured process definitions will also not be cleared up, resulting in data remaining that should not.

Environment: C7/ C8SaaS/ C8SM

Optimize version : All
ES version : All
OS + Browser version : All

Steps to reproduce:

• Preconditions: 
• Steps:
  • Add a per-process history cleanup config to Optimize for a definition key that does not exist in the engine
  • Observe the logs

Observed behavior:

The logs contain an exception and the whole history cleanup has not been applied

Expected behavior:

The logs contain a warn message, but the rest of the cleanup is applied correctly
