This is a complete rewrite of time sync process. Now the time sync process starts early at boot time, and it adapts to configuration changes: * before config is available, `pool.ntp.org` is used * once config is available, configured time servers are used Controller updates same time sync resource as other controllers had dependency on, so they have a chance to wait for the time sync event. Talos services which depend on time now wait on same resource instead of waiting on timed health. New features: * time sync now sticks to the particular time server unless there's an error from that server, and server is changed in that case, this improves time sync accuracy * time sync acts on config changes immediately, so it's possible to reconfigure time sync at any time * there's a new 'epoch' field in time sync resources which allows time-dependent controllers to regenerate certs when there's a big enough jump in time Features to implement later: * apid shouldn't depend on timed, it should be started early and it should regenerate certs on time jump * trustd should be updated in same way Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
