This patch causes Issuer DN to be stored in certificate records
using existing (unused) 'issuerName' attribute schema.
This will allow me to change sub-CAs implementation to a shared
certificate repo which means I don't have to worry about range
management anymore :) But I think it is a sensible change in its
own right.
UI / CLI filters for issuer can come later - there's a TODO for that
on my tracking etherpad[1] and I will file a ticket later.
