Add NotAllowed error for cert replace interface

Error xyz.openbmc_project.Common.Error.NotAllowed is going to be used
in phosphor-certificate-manager in certificate replacement handler.
This patch is about adding such error to the list of handled errors.

Tested by certificate replacement fault injection (replacing with
certificate with ID/hash already existing on the certificate list) using
RF API for certificates managment.
