Using 'bindaddress' in the /etc/chrony/chrony.conf disables both
client and server ntp functionality as it cannot get the ntp
responses from peer servers. The default install will leave the
servers unsynced with an ntp source causing them to skew over
time and eventually break services that rely on synced time.
Setting 'port 0' will disable the server functionality. Using
'bindcmdaddress' will still chronc<->chronyd communictions over
localhost only. This should allow client functionality and
disable server functionality.
