Bug 1377121

+++ This bug was initially created as a clone of Bug #1183624 +++

Description of problem:
With new ntpd and chronyd versions that are included starting in Fedora 22, the default configuration files changed to use the pool directive instead of server. This is used to specify a group of NTP servers where unreachable servers are replaced automatically. Instead of the four individial servers specified in the config 

server 0.fedora.pool.ntp.org iburst
server 1.fedora.pool.ntp.org iburst
server 2.fedora.pool.ntp.org iburst
server 3.fedora.pool.ntp.org iburst

there is just one pool directive

pool 2.fedora.pool.ntp.org iburst

It would be nice if system-config-date supported this. I'm not sure what would be the best way to present this to the user, maybe a checkbox for each entry that would switch between pool and server? Or resolve the name and see if the name resolves to multiple IPv4/IPv6 addresses to select it automatically?

Display four servers with the same name for each pool directive. When writing config, count servers with the same name and select pool or server directive as appropriate.

The pool directive is now used in the default chrony.conf (chrony-2.0-0.2.pre1). 
The name used is 2.fedora.pool.ntp.org, because it's currently the only one returning IPv6 addresses.

ntp will follow after update to 4.2.8.
