Description Michael Grandjean

It is possible to include so-called "CRL distribution points" in Certificates. These contain an http or ldap URI pointing to the Certificate Revocation List (CRL):

https://www.openssl.org/docs/apps/x509v3_config.html#CRL_distribution_points_

Since we already provide the CRL via "http://<hostname>/ucsCA.crl" we should include this hint where to find the CRL also in the Certificate itself.

FYI: in the Baseline Requirements of the CA/Browser Forum, CRL distribution points are mandatory:

> cRLDistributionPoints
> This extension MUST be present and MUST NOT be marked critical. 
> It MUST contain the HTTP URL of the CA’s CRL service.

There is a Customer ID set so I set the flag "Enterprise Customer affected".
