Provide components for cert management with modern XCC
Refresh getcsr and installcert to handle latest firmware. Also add ability to have pre-existing CSR, and trust the SAN on the way through. If this becomes more properly a feature, then would likely impose a SAN on certs, similar to the SSH principals, rather than deferring to the CSR to get it right.
