Lucas Alvares Gomes 373a27163e Replace chronyc "waitsync" with "makestep"
Prior to this patch we had the "chrony waitsync" command with a
hardcoded timeout of "20". Sometimes that wasn't enough when deploying
on some slower machines in my experience [0].

This patch is changing the "waitsync" command to "makestep", that way
we tell chronyd to make the system clock correct immediately (instead
of gradually correcting the time). It should be fine for our usecase
because these are ran during the deployment.

description: NTP servers list. Defaulted to a set of pool.ntp.org servers
in order to have a sane default for Pacemaker deployments when
not configuring this parameter by default.

default: []
description: NTP pool list. Defaults to [], so only NtpServer is used by
default.

type: string
description: >
Uses cloud-init to bootstrap timesync configuration to ensure it is done
as soon as possible. We do additional and more complex configurations as
part of the deployment itself.
