4375ef860f Split x509.load_certificate() into PEM/DER functions
Splitting the load_certificate() function into two separate helps
us word the requirements for the input explicitly. It also makes
our backend similar to the one of python-cryptography so eventually
we can swap python-cryptography for IPA x509 module.

3d01ec14c6 Allow full customisability of IPA CA subject DN
Currently only the "subject base" of the IPA CA subject DN can be
customised, via the installer's --subject-base option.  The RDN
"CN=Certificate Authority" is appended to form the subject DN, and
this composition is widely assumed.

Some administrators need more control over the CA subject DN,
especially to satisfy expectations of external CAs when the IPA CA
is to be externally signed.

This patch adds full customisability of the CA subject DN.
Specifically:

- Add the --ca-subject option for specifying the full IPA CA subject
  DN.  Defaults to "CN=Certificate Authority, O=$SUBJECT_BASE".

- ipa-ca-install, when installing a CA in a previous CA-less
  topology, updates DS certmap.conf with the new new CA subject DN.

- DsInstance.find_subject_base no longer looks in certmap.conf,
  because the CA subject DN can be unrelated to the subject base.
