FreeIPA server is time synchronization client only
    
    This will change behaviour that FreeIPA server will be no more
    ntpd server and time service is no longer part of FreeIPA topology.
    
    As dependency for ntpd was completely removed, and there is only
    dependency for chrony, FreeIPA will configure every host to
    became chronyd service's clients.
    
    FreeIPA have not supported --ntp-server option now it must to
    support client configuration of chrony.
    
    Configuration of chrony is moved to client-install therefore
    NTP related options are now passed to the ipa-client-install
    script method sync_time which now handles configuration of chrony.
    
    Server installation has to configure chrony before handling
    certificates so there is call to configure chrony outside of
    using server's statestore and filestore.
    
    Removed behavior that there is always --no-ntp option set.
