[Observium] Cannot create RRD for type exim - not found in definitions

Below output is from rolling release 20.6.10499.

Trying to add Exim stats via the Unix agent. Seems RRD definitions are missing for the 'exim' application, they only exist for the 'exim-mailqueue' application'.

See below the related debug output of poller.php
