[clock] introduce mini_chronyd
This patch introduces a wrapper around chronyd, so it's possible to run
multiple instances of chronyd reference NTP servers as part of Kudu
mini-cluster, providing reference for NTP clients.
One nice feature that chronyd has is its ability to run in server-only
mode, i.e. not driving the system clock: see '-x' option 'man chronyd'.
Also, it's possible to run using the system clock as a source instead
of a physical device (GPS, oscillator, etc.). In addition, it's
possible to manually set the reference time for chrony NTP server
running in server-only local mode. The chrony suite has 'chronyc' CLI
tool to send control commands to chronyd NTP daemon.
WIP:
* add more tests
* add more useful functionality to use for follow-up tests running
built-in NTP client
