    Update to 0.76.6:
    - avoid premature exit on CA data analysis failures (should fix issue
      reported by Natxo Asenjo)
    - fixes for bugs found by static analysis
    - rework the state machine so that we save an issued certificate's associated
      CA certificates, then re-read the certificate, then run the post hook and
      issue notifications, in that order, instead of saving CA certificates after
      running the post hook, which was always a surprising order (#1131700)
    - add a generic dogtag-submit helper that doesn't include any IPA defaults,
      to make it easier to know the difference between paramenters it requires
      and parameters which are optional
    - ipa-submit: when we fail to locate/contact LDAP or XML-RPC servers,
      use discovery to find them (#1136900)
    - require a single certificate to be specified to 'getcert status' (#1148001)
    - shorten the default help message which getcert prints when it's not given
      a specific command (#1131704)
    - add private listener (-l, -L, -P) mode to certmonger, to allow it to listen
      for connections directly from clients running under the same UID
    - add a command mode (-c) to certmonger, in which once it's started, it
      launches a specified command, and after that command exits, the daemon exits
    - when getcert is invoked with no bus running, if it's running as root, run
      certmonger in private listener mode with the same invocation of getcert as
      the command to start and wait for (#1134497)
