IMO explicit is better than implicit, so instead of introducing 
additional magic around --subject, I would rather add a new separate 
option for specifying the CA subject name (I think --ca-subject, for 
consistency with --ca-signing-algorithm).

By specifying the option you would override the default "CN=Certificate 
Authority,$SUBJECT_BASE" subject name. If --external-ca was not used, 
additional validation would be done to make sure the subject name meets 
Dogtag's expectations. Actually, it might make sense to always do the 
additional validation, to be able to print a warning that if a 
Dogtag-incompatible subject name is used, it won't be possible to change 
the CA cert chaining from externally signed to self-signed later.
