Force immediate NTP time sync with chronyd at IPA startup
In order to make sure we have the correct time early, e.g.
by the time we create a TLS certificate, this patch proposes
to force an immediate NTP update when using chronyd. While
the previous approach uses the passed NTP server as well, the
update may happen only after chronyd has performed measurements
(which may be too late).

Fixes an issue where the NTP time sync at the IPA startup via chronyd is
|

not immediate (which can break time sensitive components such as the
|

generation of a TLS certificate).
