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.
