[Users] ovirt-engine certs

How can I regenerate the ovirt engine CA certs and corresponding vdsm certs? I have an ovirt setup that I'm upgrading from 3.2.0 (from the dre repos) to 3.2.3 and I am getting the certificate errors listed below after the upgrade. I have done this same upgrade on an number of other ovirt-engines with no issue. The setup had originally been installed with ovirt 3.1 so it possible that some of the certificate configurations from 3.1 are still present on this ovirt-engine and it is contributing to the problem. For example, I noticed that the /etc/pki/ovirt-engine/cacert.conf file on this troublesome upgrade has "default_bits = rsa:1024", but the systems that upgraded successfully have "default_bits = rsa:2048". The same is true for the cert.conf file.
