Change subject: [WIP] KUDU-2242 Wait for NTP synchronization on startup
......................................................................


Patch Set 1:

> I wonder if we should condition this on either the system uptime or
 > the uptime of the ntpd/chrony process?

Does that mean you think there's too little realistic chance of Kudu starting 
up after the machine has been up for a while and NTP is temporarily 
unsynchronized?

I've seen a cluster in the wild where NTP had brief problem periods, though in 
that case the clocks stayed synchronized but the error bounds got big (which 
crashed the cluster).

> Also perhaps we can detect when it's not running at all, and not wait?

That should already basically happen at least for ntp-wait since it will fail 
immediately if it can't connect to the ntp daemon. I have to test it for chrony.
