Move from everything in a single /etc/chrony.conf to a split up with
configuration and server snippets. The latter comes in the form of
configured (static) and DHCP client (dynamic) server setup.
To accomodate this new scheme we need to detect when serves are removed
from the configuration, so not only have the whole change_ntp() been
refactored, it has been extended with a new pass.

Chrony drops privs after startup to user chrony, when restarting it
writes its state in /var/lib/chrony, so the directory needs to have
the correct permissions for that user.
