system_certmanager.php: Certificate list should show SANs, KU, and EKU for certificates
The list of certificates should show at least the Subject Alt Names, Key Usage, and Extended Key Usage fields for a certificate. Currently there isn't any way in the GUI to see these, a user has to export the certificate and view it locally.
I have some code to print the info. It would be nice to hide it in an info block, but it does not work yet. See #7504
