User-defined certificate subjects

Let the user, upon installation, set the certificate subject base
for the dogtag CA. Certificate requests will automatically be given
this subject base, regardless of what is in the CSR.

The selfsign plugin does not currently support this dynamic name
re-assignment and will reject any incoming requests that don't
conform to the subject base.

The certificate subject base is stored in cn=ipaconfig but it does
NOT dynamically update the configuration, for dogtag at least. The
file /var/lib/pki-ca/profiles/ca/caIPAserviceCert.cfg would need to
be updated and pki-cad restarted.
