[Bug 1263703] [NEW] Warn on noquery in ntp.conf

[DustWolf]

Public bug reported:

The "restrict" row comments of the default /etc/ntp.conf configuration
file should more explicity warn(!) against the dropping on "noquery" or
similar options, because their removal might cause the server to become
vulenrable to (become a party in) DoS attacks.

Many admins have mistakenly removed the block, thinking they have either
enabled the server to be queried from the subnet in question or made it
more usable by doing so. This resulted in a number of reflection attacks
via NTP we have been seeing in the past few days.

** Affects: ntp (Ubuntu)
     Importance: Undecided
         Status: New

** Information type changed from Private Security to Public
