Custom attributes to pass additional values

Use custom_oids_excluded_from_cert to define custom attributes that can be included in an enrollment request but are not added to the issued certificate.

This capability is particularly useful for enrollment protocols such as EST, SCEP, and CMPv2, where the request is limited to a certificate signing request (CSR).

Custom attributes enable applications to provide additional enrollment metadata required for processing, validation, or integration purposes without affecting the certificate contents.
