[libvirt] [PATCH 02/13] conf: Introduce migrate_tls_x509_cert_dir



Add a new TLS X.509 certificate type - "migrate". This will handle the
creation of a TLS certificate capability (and possibly repository) to
be used for migrations. Similar to chardev's, credentials will be handled
via a libvirt secrets.
