Description of problem:  During client install with the --no-ntp option, I see
the following messages:
Synchronizing time with KDC...
Unable to sync time with IPA NTP server, assuming the time is in sync.


Version-Release number of selected component (if applicable): 2.2


How reproducible:  Every time I install the client with --no-ntp


Steps to Reproduce:
1.  ipa-client-install --domain=blah --mkhomedir -w blah --realm=BLAH --no-ntp
--server=ipaserver.blah --unattended
2.
3.

Actual results:
Synchronizing time with KDC...
Unable to sync time with IPA NTP server, assuming the time is in sync.


Expected results:
Not sure - but something along these lines:
"Time configuration skipped."


Additional info:
Might be worth putting in an `ntpq -p` type check if the user has requested to
skip NTP configuration.  If no synced time servers can be found, warn the user
that time sync is unavailable on this client.
